Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Derivation of the Vlasov equation from quantum many-body Fermionic systems with singular interaction
奇异相互作用 量子多体 费米子系统 弗拉索夫方程
2023/4/13
We consider the combined mean-field and semiclassical limit for a system of the N fermions interacting through singular potentials. We prove the uniformly in the Planck constant h propagation of quant...

2021/11/1
Dzyaloshinskii-Moriya（DM）相互作用，是一种反对称自旋交换作用，于上个世纪六十年代由I. Dzyaloshinskii利用唯象理论提出，并由T. Moriya在超交换相互作用中考虑自旋轨道耦合而发展的微观理论，被用来解释磁性体系中诸多新奇物理现象（自旋玻璃中的各向异性场、多铁性材料中的磁电耦合、自旋波的非对称色散关系、非共线磁结构等）。近十几年来，由于DM相互作用而实现的螺旋...

2014/12/20
The nonleptonic weak ∣ΔS∣=1 ΛN interaction, responsible for the dominant nonmesonic decay of all but the lightest hypernuclei, is studied in the framework of an effective-field theory. The long-range ...

Model of fermion monte carlo simulation electric automatic way
2014/12/20
For some models of interacting fermions the known solution to the notorious sign problem in Monte Carlo (MC) simulations is to work with macroscopic fermionic determinants; the price, however, is a ma...

Quantization vortex superfluids vortex dynamics launch elementary excitation inelastic scattering acoustic radiation fluid turbulence
2014/12/20
Kelvin waves—helical waves on quantized vortex lines—are the normal modes of vortices in a superfluid. At zero temperature, the only dissipative channel of vortex dynamics is phonon emission. Starting...

2014/12/20
The “canonical” variables of the Kosterlitz-Thouless theory—fields Φ0(r) and φ(r), generally believed to stand for vortices and phonons (or their XY equivalents, like spin waves, etc.) turn out to be ...
