Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Some boundary effect in Vlasov equations
弗拉索夫方程 边界效应 统计力学
2023/4/21
We discuss a stabilizing effect of boundary in the context of Vlasov equations: 1) linear Vlasov equation with the diffuse reflection boundary condition, 2) nonlinear Vlasov-Poisson equation with infl...
Temporal disorder in up-down symmetric systems
Temporal disorder in up-down symmetric systems
2012/2/27
The effect of temporal disorder on systems with up-down Z2 symmetry is studied. In particular, we analyze two well-known families of phase transitions: the Ising and the generalized voter universality...
We examine energy transport in an ensemble of closed quantum systems driven by stochastic perturbations. One can show that the probability and energy fluxes can be described in terms of quantum advect...
Dynamics of Energy Fluctuations in Equilibrating and Driven-Dissipative Systems
Dynamics Energy Fluctuations Equilibrating Driven-Dissipative Systems
2012/2/27
When two isolated system are brought in contact, they relax to equilibrium via energy exchange. In another setting, when one of the systems is driven and the other is large, the first system reaches a...
We study the properties of mixed states obtained from eigenstates of many-body lattice Hamiltonians after tracing out part of the lattice. Two scenarios emerge for generic systems: (i) the diagonal en...
