26 DEPHASING DUE TO NUCLEAR SPINS IN LARGE-AMPLITUDE EDSR Electric manipulation of spins in quantum dots can be achieved using Electric Dipole Spin Resonance (EDSR). The local control and the fast timescales allowed by EDSR might prove decisive advantages with respect to alternative approaches for single-spin manipulation. Therefore, this technique may become a cornerstone in complex architectures of many quantum dots, which are a promising platform to implement quantum information processing . To further improve the performance of EDSR, it is necessary to characterize dominant dephasing mechanisms. An especially interesting limit is the strong electric drive regime, which was recently achieved experimentally [2, 3] and allows to further reduce the spin manipulation times. However, the main sources of noise are still poorly understood in this regime. A recent References  D. Loss and D. P. DiVincenzo, Phys. Rev. A 57, 120 (1998).  J.W. G. van den Berg, et al., Phys. Rev. Lett. 110, (2013).  J. Yoneda, et al., Phys. Rev. Lett. 113, (2014).  S. Chesi, L.-P. Yang, and D. Loss, Dephasing due to Nuclear Spins in Large- Amplitude Electric Dipole Spin Resonance, Phys. Rev. Lett. 116, (2016), (pub. 12 February 2016). DOI: / PhysRevLett investigation , involving Stefano Chesi and Li-Ping Yang of CSRC and Daniel Loss from Basel University, has developed a comprehensive theory of dephasing caused by nuclear spins in EDSR, revealing new surprising features which appear in the strong-drive regime. Nuclear spins are known for about 10 years as a dominant source of dephasing in quantum dots, but the general understanding has been that nuclear noise perpendicular to the direction of the external magnetic field has a negligible effect. On the other hand, the results of Ref.  show that the transverse nuclear noise becomes increasingly more effective at large drive strength, and eventually dominates over the longitudinal nuclear fluctuations. The presence of strong transverse noise causes qualitative and quantitative changes in the observed behavior of dephasing, which are in agreement with experiments. In fact, the theory developed in  has allowed to explain the decay of Rabi oscillation observed in recent EDSR experiments performed in Delft  and the University of Tokyo , which reached for the first time the strong drive regime. Despite the additional noise from transverse nuclear fields, EDSR remains a promising technique. As shown in , increasing the drive strength is always beneficial for accurate spin manipulation because the shorter operation time more than compensates the reduced coherence time. Fig. 1.

27 PROBINGLOCALIZATION- DELOCALIZATION IN DISORDERED ISOLATED FERMIONIC SYSTEMS OUT-OF- EQUILIBRIUM When isolated quantum systems are taken out of equilibrium, its dynamics can be described by a time evolution which is unitary, unlike classically chaotic systems. The conditions that lead these systems to thermalize and the information regarding its initial preparations to be lost over the course of its evolution can be seen as result of the dephasing in the dynamics of the coherence between the eigenstates. Its mathematical basic grounds were fundamented in what we call nowadays as the Eigenstate Thermalization Hypothesis (ETH) [1, 2] and it became clear that interactions between the constituents of the system are essential in the thermalization mechanism. On the other hand, much attention has also been given to another aspect that may, in fact, prevent thermalization. When disorder comes into play an isolated quantum system can experience a halting of thermalization and, ultimately, localization takes place. This localization is manifest in the absence of mass transport and it can be seen as a generalization of the famous Anderson localization phenomenon when interactions are included. Several numerical studies have shown this localization in the presence of interactions , which we dub as many-body localization (MBL), and also a handful number of experiments  have also tackled it. In the latter, the analyzed quantum system is consisted of atoms trapped in a potential generated by laser beams in an optical lattice. By introducing disorder on the onsite energy levels one can emulate the physics of the Anderson model with interactions which can be tuned in a controllable fashion. The most common way to identify this localization (and the associated lack of thermalization) is to follow the dynamical properties of a carefully prepared quantum system. Specifically, experiments in optical lattices employ high-fidelity preparation of initial states whose properties are well known, as for example, by confining the atoms in certain regions of the trapping environment. By measuring how the information of the initial prepared state is preserved for long-times after the release of this constraint one is able to identify the regimes where disorder is sufficient to lead to the MBL phenomenon. This has been shown to be the case experimentally and numerically when dealing with disorder as mathematically interpreted as a random scalar potential. can also display localization as is observed in the random scalar potential case. In a recent publication , Chen Cheng and Rubem Mondaini from CSRC have investigated one of the first evidences of the interplay between interactions and a random vector potential in a quasi-one dimensional system. Specifically they tackled the problem of localization and thermalization in a triangular ladder (see cartoon in Fig. 1(a)) which hosts interacting spinless fermions whose flux per triangular plaquette is chosen at random within an uniform distribution with amplitude Φ, signifying the disorder amplitude. The actual On the other hand, the latest advancements in atomic control and manipulation in optical lattices has allowed the emulation of a vector potential in these systems via the exploration of the internal degrees of freedom of these atoms, that generates an effective synthetic lattice in larger dimensions.

This is an ongoing research being currently investigated at CSRC. where and represent the hopping amplitudes, the magnitude of the nearest neighbor inter-site interactions and the fluxes associated with the site-dependent disordered vector potential. In the absence of interactions, this system is known to display localization (à la Anderson) for all energies away from singular points in the density of states, as in the random flux model. This is referred as marginal Anderson localization. To probe whether this localization survives the effect of interactions, as in the experiments, we initially prepare this quantum system in a particular state by allowing the atomic occupancy only in sites in one of the chains that compose the ladder:, which represents a fully formed charge density wave. An observable that quantifies this initial information is called the mass imbalance which measures the different occupancies in even and odd sites of the lattice. By tracking whether the initial information is preserved or not after long time evolution, one can unquestionably specify whether localization takes place or not. In Fig. 1(a), we display the time dependence of the average mass imbalance for the largest possible disorder amplitude and different values of the interaction. For the proposed initial state, the initial value of the imbalance is 1 and we see that it eventually decays, equilibrating to values close to 0. To make sure that all the initial information is lost over the course of the time evolution, we systematically check the finite size effects of the infinite time-average (often called diagonal ensemble - DE) of the imbalance in the inset of panel (b). In the thermodynamical limit, it is clear that all the initial information is completely lost even for values of the interactions of the order of 2% of the noninteracting bandwidth. We then summarize by noticing that the random vector potentials although lead to localization for non-interacting particles, delocalization takes place when interactions are included, no matter how strong is the disorder associated with the vector potentials. This is an effect completely different from the standard case of random scalar potentials and we expect it to be soon verified in actual optical lattice experiments.
29 A TENSOR PRODUCT STATE APPROACH TO SPIN-1/2 SQUARE J 1 -J 2 ANTIFERROMAGNETIC HEISENBERG MODEL: Evidence For Deconfined Quantum Criticality The ground state phase of spin-1/2 J 1 -J 2 antiferromagnetic Heisenberg model on square lattice around the maximally frustrated regime (J 2 ~ 0.5J 1 ) has been debated for decades. Here we study this model using the cluster update algorithm for tensor product states (TPSs). The ground state energies at finite sizes and in the thermodynamic limit (with finite size scaling) are in good agreement with exact diagonalization study. Through finite size scaling of the spin correlation function, we find the critical point J2 c1 = 0.572(5)J 1 and critical exponents ν = 0.50(8), η s = 0.28(6). In the range of < J 2 /J 1 < 0.6 we find a paramagnetic ground state with exponentially decaying spin-spin correlation. Up to system size, we observe power law decaying dimer-dimer and plaquette-plaquette correlations with an anomalous plaquette scaling exponent η p = 0.24(1) and an anomalous columnar scaling exponent η c = 0.28(1) at J 2 /J 1 = 0.6. These results are consistent with a potential gapless U(1) spin liquid phase. However, since the U(1) spin liquid is unstable due to the instanton effect, a VBS order with very small amplitude might develop in the thermodynamic limit. Thus, the numerical results strongly indicate a deconfined quantum critical point (DQCP) at J 2 c1. Remarkably, all the observed critical exponents are consistent with the J Q model. References : L.

30 HIDDEN QUANTUM MIRAGE BY NEGATIVE REFRACTION IN SEMICONDUCTOR P-N JUNCTIONS Half a century ago, Veselago  proposed the concept of negative refraction for electromagnetic waves: a sharp interface between a medium with positive refractive index and a negative index medium could refocus a diverging pencil of rays to form an image or quantum mirage, similar to the bending of light to create mirages in the atmosphere. In 2007, Cheianov et al.  shows that a sharp and specular graphene P-N interface can exhibit anomalous focusing and produce a quantum mirage. This effect has been widely used in theoretical proposals to control charge and/or spin transport for massless Dirac fermions in semiconductors. However, over many years anomalous focusing has not been clearly confirmed in experiments until very recently , because of its fragility to the finite width and disorder Fig. 1. Graphene P-N junction in real space (a) and gate-induced shift of the Dirac cones in momentum space (b). The quantum mirage is visible in a sharp P-N junction (c), but is gradually smeared out in a smooth junction (d). Fig. 2.

Recently, Wen Yang and Haiqing Lin s group in CSRC in collaboration with Kai Chang s group in the Institute of Semiconductors, CAS proposed a new interference phenomenon observable in a wide range of semiconductor P-N junctions . Compared with the interface-induced anomalous focusing, this phenomenon enjoys two distinguishing features [see Fig. 2(a) and (b)]. First, it originates from the symmetry of the Fermi surfaces of the constituent materials, so it is insensitive to the details of the interface, such as the width, potential profile, and even disorder. Second, it does not produce a visible quantum mirage, but instead can be detected as a distance-independent response across the P-N interface, in sharp contrast to the nearly universal 1/R (d 1)/2 decay with distance R of the response in d-dimensional uniform systems. The predicted phenomenon could dramatically enhance many response properties in various semiconductors. The recently fabricated P-N junctions in 2D semiconductors provide ideal platforms to explore this phenomenon and its applications to dramatically enhance charge and spin transport as well as carrier-mediated long-range correlation between localized magnetic moments.
31 PHOTOELECTRIC CONVERTERS WITH QUANTUM COHERENCE Carnot s theorem states that all real heat engines operating between two heat baths undergo irreversible processes and are less efficient than a reversible heat engine, regardless of the working substance used or the operation details. Numerous studies have attempted to design more efficient heat engines and improve the work extraction when quantum effects come into play 1. Most of quantum thermodynamic studies only emphasized on achieving a conversion efficiency limit, which is inevitably accompanied by vanishing power output 2. More extensive research needs to be conducted regarding the interdependence of efficiency and power for practical applications. Based on the Newton heat transfer law, Curzon and Ahlborn found that the efficiency at maximum power of an endoreversible Carnot heat engine with irreversible heat transfer processes is given by η CA = 1-T c / T h, where T h is the temperature of the heat source and T c is the temperature of the heat sink 3. Other various thermodynamic machines indicate that η CA gives a good approximation for estimating the efficiency at maximum power 4. In particular, Rutten et al. proved that the efficiency at maximum power of a nanosized photoelectric converter can be well predicted by the Curzon and Ahlborn efficiency 5. Only in the case of the strong coupling condition between electron and heat flows and negligible nonradiative effects, can the efficiency more closely approach to η CA. of the thermodynamic analysis show that the quantum coherence is capable of improving the efficiency beyond the limit of a system whose quantum effects are absent. Particularly, the efficiency at maximum power is no longer limited to η CA through the manipulation of An interesting question arises here: might quantum coherence survive stably in nano-electronic systems and help to increase the efficiency at maximum power beyond the bound of the Curzon and Ahlborn efficiency? By considering a three-level quantum dot (QD) in thermal contact with two boson reservoirs, Li et al. confirmed that the interferences of two transitions in a non-equilibrium environment can give rise to non-vanishing steady quantum coherence 6. Noise-induced coherence is capable of breaking the detailed balance condition and enhancing the laser power of a quantum heat engine 7. The efficiency at maximum power of the laser quantum heat engine has been shown to depend on the proper adjustment of the coherence parameters 8. In these previous studies, the interaction between quantum systems and bosonic baths plays a key role in generating coherence. However, whether an electronic system in a fermionic environment enables the realizations of steady coherence and performance improvement is rarely discussed. Fig. 1. The absolute value of coherence (a) and the efficiency (b) as a function of the dimensionless strengths of coherences r P and r l. Prof. Chang-Pu Sun's group in CSRC apply quantum effects to design a photoelec-tric converter based on a three-level QD under nonequilibrium environment. We show that, by adopting a pair of suitable degenerate states, quantum coherences exist steadily in nano-electronic systems. It follows from the Born-Markov approximation that the interference due to coherent transitions can be simultaneously induced by the sunlight and the left-fermionic bath, leading to two different nondiagonal terms in the Lindblad-like master equation.

33 MAGNON KERR EFFECT IN A STRONGLY COUPLED CAVITY-MAGNON SYSTEM Hybridizing two or more quantum systems can harness the distinct advantages of different systems to implement quantum information processors 1. Recently, a cavity microwave photon-magnon system has attracted considerable attention (see, e.g., Refs. 2-4), because of the enhanced coupling between magnons in an yttrium iron garnet (YIG) single crystal and microwave photons in a high-finesse cavity. Based on the strongly coupled cavity-magnon system, coherent interaction between a magnon and a superconducting qubit was realized 5, and magnon dark modes in a magnon gradient memory 6 were utilized to store quantum information. Potentially acting as a quantum information transducer, microwave-to-optical frequency conversion between microwave photons generated by a superconducting circuit and optical photons of a whispering gallery mode supported by a YIG microsphere was also explored 7. Now, a versatile quantum information processing platform based on the coherent couplings among magnons, microwave photons, optical photons, phonons, and superconducting qubits is being established. explore nonlinear effects in the cavity-magnon system. This work was supported by the National Key Research and Development Program of China However, all the outcomes were achieved in the linear regime. An extension of the cavity-magnon system to the nonlinear regime is expected to show interesting nonlinear effects in this system. Here Prof. Tie-Fu Li and Prof. Jian-Qiang You's group in CSRC report an experimental study of the nonlinear effect in a coupled cavity-magnon system at cryogenic temperature. The nonlinearity comes from the magnetocrystalline anisotropy of the YIG sphere, which corresponds to the Kerr term in the derived Hamiltonian of the system. The YIG sphere is attached on the inner wall of a three-dimensional rectangular cavity and the magnons in the YIG sphere are strongly coupled to the cavity microwave photons. When the YIG sphere is pumped to generate considerable magnons, the Kerr effect yields a perceptible shift of the cavity s central frequency and more appreciable shifts of the magnon modes. They derive an analytical relation between the magnon frequency shift and the drive power for the uniformly magnetized YIG sphere: where is the frequency shift of the magnon mode, is the damping rate of the magnon mode is the power of the microwave drive field on the YIG sphere, and is a constant that reflects the coupling strength between the drive field and the YIG sphere. They found that it agrees very well with the experimental results of the ferromagnetic resonance mode (i.e., Kittel mode) of the YIG sphere. Our study paves the way to (1) Fig. 1.

35 METALLIC GLASS AS HIGH PERFORMANCE CATALYST FOR HYDROGEN PRODUCTION Hydrogen is one of the most promising and appealing alternative energy resources of fossil fuels to tackle the current energy crisis and environmental issues. Electrochemical water splitting with high efficient catalyst is one of the main methods to produce hydrogen. How to improve the performance of the catalysts, including the activity and durability, is crucial for promoting the application of hydrogen energy. The currently reported catalysts including the commercial Pt/ C catalyst are mainly crystalline, in which the activity is influenced by the metastable local structures. Recently, by combining experimental characterizations and theoretical computations, the research group lead by Prof. Peng-Fei Guan at Beijing Computational Research Center (CSRC), collaborated with Prof. Wei-Hua Wang s group in Institute of Physics, Chinese Academy of Sciences, and Prof. Chun-Wen Sun s group in Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, National Center for Nanoscience and Technology (NCNST), discovered that metallic glass could be highly efficient and self-stabilizing catalyst for water splitting. The work is mainly done by the visiting student, Yuanchao Hu and the postdoc, Rui Su of our Center. Metallic glasses are amorphous materials fabricated by rapidly quenching the hightemperature melts. The disordered structure gives rise to their outstanding mechanical and physical properties, such as high strength, excellent corrosion resistance and superior soft magnetism etc. In addition, this latest research shows the astonishing potential of metallic glasses as functional materials to catalyze electrochemical reactions. Based in the computational simulations, we unveil the underlying atomicscale mechanism of the excellent comprehensive performances of the amorphous alloys, which provides new approaches for designing novel catalysts with better performance.

Botton*, and Xueliang Sun*, Nature Commutations, 7, (2016). (#equal contribution to this work). Hydrogen is generally thought to be one of the most promising energy sources of the 21st century, and platinum-based catalysts are widely considered to be the most effective electrocatalysts for the hydrogen evolution reaction (HER). Unfortunately, Pt is expensive and scarce, limiting the commercial potential for such catalysts. In order to overcome the challenges associated with the Pt HER catalysts and to drive the cost of H2 production down from water electrolysis, it is very important to dramatically decrease the Pt loading and increase the Pt utilization efficiency. Currently, the typically supported Pt nanoparticles (NPs) catalyst limit the majority of the Pt atoms to the particle core, deeming them ineffective as only surface atoms are involved in the electrochemical reaction. Thus, further reducing the size of the Pt NPs to clusters or even single atoms to decrease the noble metal usage and increase their catalytic activity is highly desirable. However, in practical applications, controlled and large-scale synthesis of stable single atoms and clusters remains a considerable challenge due to the natural tendency for these active metal atoms to diffuse and agglomerate. A group of researchers at CSRC, led by Dr. Li-Min Liu, has worked together with Prof. Xueliang Sun group at University of Western Ontario and Prof. Gianluigi A. Botton at McMaster University to explore an effective means to synthesize the stable single-atom catalyst on a large scale. Utilizing a combined aberration corrected scanning transmission electron microscopy (STEM) and density functional theory (DFT) calculations, the atomic layer deposition (ALD) technique has been proven to successfully fabricated single Pt atoms supported by nitrogen-doped graphene nanosheets (NGNs) for the HER. From DFT analysis, the stabilization mechanism of single Pt atom on N-doped graphene was uncovered. They have discovered that the remarkable performance of the single Pt atoms on the NGNs arise from their small size and the unique electronic structure originating from the partially unoccupied density of states of the platinum atoms 5d orbitals. This study paved the way for the investigation of the electrocatalytic activity
37 UNCOVER THE EFFECTIVE CONFINEMENT OF LITHIUM-POLYSULFIDES AND ENHANCED REACTION KINETICS OF SULFUR ON HOLLOW NANOSPHERES Lithium-sulfur (Li-S) batteries exhibit great advantages for next generation electrical energy storage and conversion due to their high theoretical energy density, low cost and environmental friendliness. However, the commercialization of the rechargeable Li-S battery is still hindered by several issues such as the inherent poor electronic conductivity of sulfur and its discharge products (Li2S/Li 2 S 2 ), the dissolution of intermediate lithium polysulfides (LiPSs), as well as the large volumetric expansion upon full lithiation. Thus, it is vital to enhance the conductivity of the sulfur cathode and moderate the dissolution of lithium polysulfides for the application of lithium-sulfur batteries. A group at CSRC, led by Dr. Li-Min Liu, has worked together with Prof. David Lou s group at Nanyang Technological University, and they discovered a new sulfur host based on highly conductive polar hollow nanospheres for lithium-sulfur batteries. This host can maximize the effectiveness of moderating LiPSs diffusion and enhance the redox reaction kinetics of sulfur species at the same time. The extensive first-principles calculations and the experiments indicate that titanium hollow nanospheres with inherent metallic conductivity and strong adsorption capability for lithium-polysulfides can not only generate sufficient electrical contact to the insulating sulfur for high capacity, but also effectively confine lithium-polysulfides for prolonged cycle life. This work overcomes the major limitations associated with other polar and nonpolar sulfur hosts, and may open up the prospect of constructing more efficient nanostructures for moderating the diffusion of LiPSs and enhancing the reaction kinetics of sulfur.

38 TWO-DIMENSIONAL SIS LAYERS ARE PREDICTED TO HAVE SUPERB ELECTRONIC AND OPTOELECTRONIC PROPERTIES Converting solar energy into electricity or chemical energy with high efficiency and low cost plays an important role in our nation s long term energy security, economy, and environmental sustainability. A key issue in this endeavor is to find or design new renewable energy materials with stable structure and superb electronic and optoelectronic properties. Two-dimensional (2D) materials have many novel properties suitable for electronic and optoelectronic applications. However, all current 2D materials have shortcomings that limit their performances. For example, graphene, as the first extensively studied 2D material, has excellent carrier mobility, but its semi-metallic behavior and lack of bandgap limit its applications in electronics. Monolayer TMDs such as MoS2, show direct bandgaps and self-healing properties in air, but their less dispersive band edges with relatively localized transition metal d character result in relatively heavy carrier effective masses and thus not so good mobility for high-performance applications. Moreover, bandgaps change from being direct into indirect when TMDs change from mono- to multi-layers, thus limiting the flexibility of tuning its electronic properties through layer controls. Phosphorene and few-layer black phosphorous have shown good mobility and good flexibility of tuning properties by layer control and anisotropic engineering. However, their poor stability leads to rapid degradation when exposed to air. While much effort has been devoted to improve the properties of these current 2D materials, it is still highly desirable to find new 2D materials with exceptional material properties for renewable energy applications. Prof. Su-Huai Wei at the Beijing Computational Science Research Center, in collaboration with Dr. Ji-Hui Yang at the National Renewable Energy Laboratory and Rice University, USA, and a group led by Prof. X. G. Gong in Fudan University, have predicted, by using atomic transmutation and differential evolution global optimization methods in conjunction with first-principles density functional theory (DFT) calculations, two group IV-VI 2D materials, Pma2-SiS and silicene sulfide with superp material properties. Pma2-SiS is found to be both chemically, energetically, and thermally stable. Most importantly, Pma2-SiS has shown good electronic and optoelectronic properties, including direct bandgaps suitable for solar cells, good mobility for nanoelectronics, low thermal conductivity for thermal electric devices, good flexibility of property tuning by layer control and strain appliance, and good air stability as well. Therefore, Pma2-SiS is expected to be a promising 2D material in the field of 2D electronics and optoelectronics. The designing principles demonstrated in identifying these two tantalizing examples have great potential to accelerate finding of new functional 2D materials. Fig. 1.

40 ORIGIN OF THE PUZZLING DIFFUSION BEHAVIORS OF CU AND AG IN SEMICONDUCTORS ARE UNRAVELED Atomic diffusion is one of the critical factors in determining the performance and stability of semiconductor electronic and optoelectronic devices. Group IB elements Cu and Ag are important contact materials in semiconductor devices due to their low resistivity and high resistance to electromigration damage. However, they have very different diffusion behaviors in semiconductors: Cu diffuses much faster than Ag in covalent semiconductors like Si and GaAs, but Ag diffuses faster than Cu in more ionic II-VI semiconductors such as CdS and CdTe despite Ag has larger size than Cu. These puzzling behaviors have not only scientific interest but also technology applications because they hindered some practical application of Cu and Ag in semiconductor devices. For example, because of challenges related to the high diffusivity of Cu in Si, one has to use Ag as contact materials in Si solar cell despite Ag is more expensive. On the other hand, because Ag diffuses faster than Cu in more ionic CdTe, replacing Cu by Ag has failed because the fasr diffusion of Ag introduce instability despite Ag has better doping properties than Cu in CdTe. Despite the importance of Cu and Ag in semiconductor technology, the mechanisms behind their distinct diffusion behaviors in covalent and ionic semiconductors have not been addressed. Working with Hui-Xiong Deng, Jun-Wei Luo, and Shu-Shen Li of the Institute of Semiconductors, CAS, Prof. Su-Huai Wei at the Beijing Computational Science Research Center have unraveled the underlying mechanisms of the puzzling diffusion behavior of Cu and Ag in semiconductors by combining the first-principles calculations and group theory analysis. They show that the important roles of the Coulomb energy, strain energy, and most importantly crystal symmetry enforced s-d coupling plays important roles in determining the diffusion behaviors of Cu and Ag in the covalent and ionic semiconductors. The s-d coupling is absent in pure covalent semiconductors but increases with the ionicity of the zinc-blende semiconductors, and the coupling strength of Cu, owing to its higher d orbital energy, is much larger than Ag. In conjunction with Coulomb interaction and strain energy, the Fig. 1. The diffusion energy curves of Cu, Cu +, Ag, and Ag + in the group IV elemental compounds, Si and Ge; group III-V compounds, GaAs and GaSb; and group II-VI compounds, CdS and CdSe. The Ta and Tc sites for Cu and Ag diffusion are slightly different.
41 s-d coupling is able to explain all the diffusion behaviors of Cu and Ag in covalent to ionic semiconductors. The calculated results and explanation, therefore, provide deep understanding on the important diffusion behavior of impurity in semiconductors and enables us to engineering doping in semiconductors through diffusion, e.g., by designing alternative diffusion barriers for Cu and Ag or choosing different diffusers.

Tang, Entropy production of nanosystems with time scale separation, Phys. Rev. Lett. 117, (2016). stochastic thermodynamics have made it possible to deduce entropy production and heat transfer from the system trajectory in the full phase space. Yet only the time series of a tiny subset of system variables is usually available in experimental measurements. A question of practical importance is whether one can reconstitute the hidden energy dissipation involving the vast number of unobserved variables through a full temporal measurement of the reduced set of variables[1-4]. Recently, Shou-Wen Wang and Lei-Han Tang at CSRC, together with their Japanese collaborators Kyogo Kawaguchi and Shin-ichi Sasa, have answered the question in the affirmative for a broad class of nano systems. Their key idea is to employ the frequency spectrum of FDT violation to estimate hidden energy loss. The fluctuation-dissipation theorem (FDT) is a hallmark of systems in thermal equilibrium. Previously, Harada and Sasa established an equality to connect energy dissipation in a given viscous channel to the violation of the FDT applied to the corresponding displacement variable. One way to generate energy flow through the system, as considered in Ref. , is to stir the displacement variable of a colloidal particle with an active noise. This active noise also brings the system out of equilibrium. When the perturbation is applied on a time scale much faster than the typical relaxation time of the variable in question, the frequency spectrum of the FDT violation, which can be constructed from high frequency time series measurement of the displacement variable, exhibits a characteristic plateau as shown in Fig. 1. Stiring increases fluctuations of the displacement variable and, at the same time, produces heat flow into the fluid. FDT violation in the displacement variable thus presents the smoking gun for hidden heat flow. It turns out that the FDT violation plateau is a general feature of Markov systems whose state space can be partitioned into different coarsegrained blocks, with fast intra-block transitions and slow inter-block transitions. As the timescale separation parameter increases, the plateau extends proportionally in size while its amplitude diminishes, leaving the area underneath constant. To our knowledge, the method proposed in Ref.  is currently the only protocol that can be used to reveal hidden dissipation from partially observed trajectories. The CSRC team is actively seeking collaboration with experimentalists to carry out proof-of-principle measurements in, e.g., laser manipulated colloidal systems.
43 DIFFUSION OF ELLIPSOIDS IN BACTERIAL SUSPENSIONS The diffusion of a small tracer in a surrounding medium provides a reliable means for probing material properties of complex fluids. Particularly, such a method has been used to investigate unique features of active fluids a novel class of non-equilibrium soft materials where each individual in the system propels itself. The behavior of spherical tracers in active fluids is most clearly illustrated by the diffusion of colloidal spheres in suspensions of swimming microorganisms, which exhibit a super-diffusive behavior at short times and a dramatically enhanced translational diffusion at long times. The enhanced diffusion of passive particles such as nutrient granules, and extracellular products is of great biological importance, which maintains an active ecological balance, stimulates biomixing, and promotes intercellular signaling and metabolite transports. However, few natural particles have the perfect spherical symmetry and usually possess more than translational degrees of freedom. It is still an open question how and to what extent the enhanced translational diffusion of an anisotropic particle is influenced by other degrees of freedom, especially by its rotation. it is shown that such an anomalous diffusive behavior arises from the generic straining flow of swimming bacteria. This work illustrates an unexpected feature of active fluids and deepens the understanding of transport processes in microbiological systems. References: Y. Peng, L. Lai, Y. Tai, K. Zhang, X. L. Xu*, and X. Cheng*, Diffusion of Ellipsoids in Bacterial Suspensions. Phys. Rev. Lett. 116, (2016). Recently, the research group led by Prof. X. L. Xu at Beijing Computational Science Research Center, together with Prof. X. Cheng s group at the University of Minnesota investigated the diffusion of isolated ellipsoids in a quasi-two-dimensional bacterial bath. Their study shows a nonlinear enhancement of both translational and rotational diffusions of ellipsoids. More importantly, they uncover an anomalous coupling between particles translation and rotation that is strictly prohibited in Brownian diffusion. The coupling reveals a counterintuitive anisotropic particle diffusion, where an ellipsoid diffuses faster along its minor axis. Combining experiments with theoretical modeling, Fig. 1.

44 TOO MUCH REGULARITY MAY FORCE TOO MUCH UNIQUENESS The numerical solution of fractional-order differential equations has attracted much attention in the last 10 years; the MathSciNet database records 432 papers in this category since But there is an anomaly in almost all of this work: although it is well known that for smooth data, typical solutions of fractionalderivative initial-value and boundary value problems exhibit weak singularities at one or more boundaries of the domain, nevertheless the vast majority of published papers assume that the solutions that they approximate are very smooth globally which of course simplifies greatly their numerical analysis. This assumption of smoothness has been sold as putting only a mild restriction on the problem and thereby justifying this simplification in the analysis. But now, in a new paper, Prof. Martin Stynes at CSRC show that the smoothness assumption greatly restricts the class of problems studied and is therefore unacceptable. The type of problem that he consider in his paper is the most popular one studied in the literature: time-dependent initial-boundary value problems on a bounded domain in one space variable, where the time derivative is a Caputo fractional derivative of order α, with 0 < α < 1 (fractional parabolic type) or 1 < α < 2 (fractional hyperbolic type). For smooth and compatible data, typical solutions u(x, t) to such problems are continuous on the closed space-time domain but are weakly singular: when 0 < α < 1 the derivative u / t blows up at the initial time t = 0, and when 1 < α < 2 the derivative 2 u / t 2 blows up at t = 0. A typical solution for a fractional parabolic problem is shown in the Figure: it is continuous on the closed domain, smooth in the space variable, but its derivative u/ t becomes infinite at the initial time t = 0. The main result in our paper is that, if one assumes even slightly more regularity than is generally true of typical solutions, then the initial condition is determined uniquely by the other data of the problem which is completely unnatural. For example, if one considers the fractional heat equation with zero boundary data and an arbitrary smooth initial condition that vanishes at the two corners of the spacetime domain, then the assumption that u/ t is continuous on the closed domain will imply that the solution of the problem must be the trivial function u(x, t) 0.

45 OPTIMIZATION-BASED SHRINKING DIMER METHOD FOR FINDING TRANSITION STATES Finding transition states on a complex energy landscape, that are given by index-one saddle points of the energy,is a challenging problem that arises in various scientific fields like physics, chemistry, biology and materials science. It has attracted much attention in many interesting applications. A recent review on numerical algorithms for transition states can be found in [?]. In , Zhang and Du proposed the shrinking dimer dynamics (SDD) to compute index-1 saddle points, which may be viewed as the continuous limit of the original dimer method popularized by . Inspired by the SDD, we propose a novel optimization-based shrinking dimer (OSD) method. In the new OSD algorithm, by constructing the rotation and translation steps in the classical dimer method under an optimization framework, we are able to take advantage of more powerful optimization methods to substantially speed up the computation of transition states. Specifically, the Barzilai-Borwein gradient method  is proposed as an effective implementation of OSD. We show that the OSD method is the generalized formulation of the original shrinking dimer dynamics (SDD) and enjoys superlinear convergence. Various numerical examples are tested for both OSD and SDD methods, including some standard lower dimensional test examples, a cluster of seven particles, and nucleation in phase transformations. The results demonstrate that the OSD method with the proposed Barzilai-Borwein step size is very effective and provides a more efficient implementation than the original SDD algorithm. Our new algorithms offer potential to significantly advance the state-of-the-art in transition state search. Lei Zhang (PKU) Qiang Du Zhenzhen Zheng (Postdoc, CSRC) SIAM J. Sci.

46 EFFICIENT SPECTRAL ELEMENT METHODS FOR EIGENVALUE PROBLEMS OF THE SCHRÖDINGER OPERATOR WITH AN INVERSE SQUARE POTENTIAL The Schrödinger operator is extremely important in science and there are several different forms of this remarkable operator. The Schrödinger operator with the inverse square singular potential has attracted quite a large interest in the recent literature owing to its fundamental role both in mathematics and in physics. The inverse square potential represents an intermediate threshold between the regular potential and singular potential in nonrelativistic quantum mechanics [2,4]. Mathematically, the inverse square potential usually invokes strong singularities of the Schrödinger eigenfunctions [1,3]. In addition, the geometry of the domain such as the presence of reentrant corners also plays a critical role which may reduce the regularity of the eigenfunctions. New tools and approaches are urgently needed for such Schrödinger operators both in analysis and in numeric. A breakthrough work in this direction was recently developed by the group of Prof. Zhimin Zhang in CSRC. Consider the eigenvalue problem: where is a bounded domain in such that the origin. There are three stages in our investigation: We start from a ball of any dimension, and design our novel spectral methods with non-polynomial basis functions to fit the singularities of the eigenfunctions. This effort immediately upgrades the spectral methods for this singular problem from an algebraic order of convergence to an exponential order. I II III IV Fig. 1. Exponential order of convergence of our novel spectral method (I and II) vs. algebraic order of convergence of the traditional method (III, IV). At the second stage, we move to circular sectors in the two dimensional setting. Only in the tangential direction some modifications are needed from stage one. At the final stage, we extend the idea to arbitrary polygonal domains. We propose a mortar spectral element approach: a polygonal domain is decomposed into several sub-domains with each singular corner including the origin covered by a circular sector, in which origin and corner singularities are handled similarly as in the former stages, and the remaining domains are either a standard quadrilateral/triangle or a quadrilateral/triangle with a circular edge, in which the traditional polynomial based spectral method is applied. All sub-domains are linked by mortar elements.
47 I II III IV In all three stages, exponential convergence rates are achieved. Numerical experiments indicate that our new methods are superior to the standard polynomial based spectral (or spectral element) methods and the hp-version finite element method using geometric meshes which is known for the best convergence rate with the presence of corner singularities . Our study offers a new and effective way to handle eigenvalue problems of the Schrödinger operator including the Laplacian operator on polygonal domains with reentrant corners. Fig. 2. Meshes on various geometries (square, L-shape domain and two iso-spectral domains).

48 ENERGY QUADRATIZATION--A NEW TECHNIQUE FOR DISSIPATIVE PARTIAL DIFFERENTIAL EQUATION SYSTEMS Models for thermodynamic systems and hydrodynamic systems can be derived using a nonequilibrium thermodynamic paradigm known as the generalized Onsager principle . The models developed under this framework possess energy dissipative properties and variational structures. In order to solve the partial differential equations in the models, numerical methods should be designed in such a way to respect energy dissipation as wel as the variational structure. Such methods are called energy stable schemes. We have developed a fairly general strategy to develop energy stable numerical schemes for models derived from the generalized Onsager principle. The strategy has been applied to various model systems ranging from multiphase fluid flows to multiphase phase field models. When the system is subject to periodic boundary conditions, we have developed fully discretized energy stable schemes for multiphase and liquid crystal fluid flows. For physical boundary conditions, we have energy stable schemes for semi-discretized systems. In some of the works, a new method, which we call the energy quadratization technique, was introduced to arrive at linear energy stable schemes. Both first order and second order in time schemes are developed [1, 3-17]. These methods are shown to be more accurate and efficient compared with the non-energy stable schemes. model gives a prediction that is independent of the density ratio of the two fluid components, while the quasi-incompressible model shows the sensitivity to the density ratio. The deviation is drastic when the density ratio is large, which directly cast a doubt on the appropriateness of using the incompressible model for mixture.

50 QUANTUM MECHANICAL MODELING OF NANOSCALE LIGHT EMITTING DIODES Understanding the electroluminescence (EL) mechanism in nanoscale light emitting diodes (LED) devices is crucial to further advance the technology for more efficient lighting and enhanced communications. From the theoretical perspective, accurate description of the electricalto-optical conversion processes is a challenging task, since the system is in the non-equilibrium state driven by an optical and electric field. The prevailing studies evaluate the performance of LED devices based on classical models, relying on parameters obtained either from experiments or first-principles calculations. However, these models fail to capture quantum phenomena and break down at the nanoscale. Chi-Yung Yam's group in CSRC formulate a quantum mechanical approach for modeling the EL processes in nanoscale LED. Based on non-equilibrium Green s function quantum transport equations, interactions with the electromagnetic vacuum environment are included to describe electrically driven light emission in the devices. Taking into account the atomistic details and nonequilibrium statistics, EL spectra of nanoscale devices under different bias conditions can be simulated. Furthermore, the method offers the possibility of determining the radiation pattern and polarization of emitted light. This provides useful information for further improvement of the device performance as well as probing structural details in the junctions. The presented framework is illustrated by numerical simulations of a silicon nanowire LED device. EL spectra and emission characteristics of the nanowire device under different bias voltages are plotted in Fig.1. A single broad emission peak is observed corresponding to transitions from the conduction band to the valence band. They note that the intensity of photon emission in general increases with an applied bias voltage. For a low bias voltage, no light emission is observed. As the forward bias approaches the flat band position, electrons and holes are injected simultaneously from electrodes. For carriers injected into the device, they can either flow directly from source to drain electrodes or undergo inelastic scattering through electron photon interactions. The latter results in radiative recombination and gives rise to photon emission. The emission intensity therefore increases substantially when the applied bias exceeds the built-in potential of the system. The frequency of emitted photons is mainly determined by DOS and the electron distribution in the conduction and valence bands.
