Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Transport properties of Gaussian measures for nonlinear Schrodinger equations
非线性 薛定谔方程 高斯测度 输运性质
2023/11/13
In the statistical study of Hamiltonian PDEs out of the equilibrium (lack of invariant measures), it is a natural question to understand the transport properties for canonical Gaussian measures. The f...
Uncovering unexpected properties in a complex quantum material（图）
复杂量子材料 意外特性 Ta2NiSe5 激子绝缘体
2023/7/11
Anew study describes previously unexpected properties in a complex quantum material known as Ta2NiSe5. Using a novel technique developed at Penn, these findings have implications for developing future...
Theorists propose new class of topological metals with exotic electronic properties
Theorists topological metals exotic electronic properties
2017/2/16
Researchers at Princeton, Yale, and the University of Zurich have proposed a theory-based approach to characterize a class of metals that possess exotic electronic properties that could help scientist...
Electromagnetic properties of nucleons and hyperons in a Lorentz covariant quark model
Magnetic nuclear lorentz covariance the bound state quark let-down pseudo-scalar meson
2014/12/20
We calculate magnetic moments of nucleons and hyperons and N -> Delta + gamma transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound st...
Local Stress and Superfluid Properties of Solid 4He
Semi-quantitative simulation crystal crystal defects superfluids
2014/12/19
We provide a semiquantitative tool, derived from first-principles simulations, for answering the question of whether certain types of defects in solid 4He support mass superflow. Although ideal crysta...
Structural Analysis of Laplacian Spectral Properties with Application to Electric Transmission Networks
Laplacian Spectral Properties Electric Transmission Networks Optimization and Control
2011/8/18
Abstract: The spectrum of the Laplacian matrix of a network plays a key role in a wide range of dynamical problems associated with the network, from transient stability analysis of power networks to d...
Noncommutative kappa-Minkowski phi4 theory: Construction, properties and propagation
kappa-deformed space noncommutative quantum field theory High Energy Physics - Theory
2011/10/8
Abstract: We have constructed noncommutative phi^4 field theory on kappa-Minkowski spacetime. Quantum properties via 2-point functions were analized, and effect of birefringence for the massive scalar...
Quantum Axiomatics: Topological and Classical Properties of State Property Systems
State Property System orthocomplementation property lattice closure space classical property
2011/9/29
Abstract: The definition of 'classical state', and how it was used in earlier work to prove a decomposition theorem internally in the language of State Property Systems, presupposes as an additional d...
Understanding the Random Displacement Model: From Ground-State Properties to Localization
the Random Displacement Model Ground-State Properties Localization
2011/8/23
Abstract: We give a detailed survey of results obtained in the most recent half decade which led to a deeper understanding of the random displacement model, a model of a random Schr\"odinger operator ...

2011/9/15
A class of random graphs is introduced and studied. The graphs are constructed in an algorithmic way from five motifs which were found in [Milo R., Shen-Orr S., Itzkovitz S., Kashtan N., Chklovskii D....
Properties of a Polarization based Phase Operator
Properties of a Polarization Phase Operator
2011/9/14
We de ne a Hermitian phase operator for zero mass spin one particles (photons) by taking account polarization. The Hilbert space includes the positive helicity states and negative helicity states with...
Ground-state properties of a supersymmetric fermion chain
Ground-state properties supersymmetric fermion chain
2010/12/27
We analyze the ground state of a strongly interacting fermion chain with a supersymmetry. We conjecture a number of exact results, such as a hidden duality between weak and strong couplings. By explo...
Quantum query complexity of minor-closed graph properties
Quantum query minor-closed graph properties
2010/11/8
We study the quantum query complexity of minor-closed graph properties, which include such problems as determining whether a graph is planar, is a forest, or does not contain a path of a given length....
