Examination of classical simulations for Heisenberg-Langevin equations for spin-1/2
Scott D. Linz, Jochen Gemmer
A system of spins coupled to a bath is a traditional setup in open quantum systems. Through Heisenberg's equation, the spin dynamics can be modeled by a set of first-order differen…

Scrutinizing the Mori memory function for diffusion in periodic quantum systems
Scott D. Linz, Jiaozi Wang, Robin Steinigeweg +1
Diffusion is an ubiquitous phenomenon. It is a widespread belief that as long as the area under a current autocorrelation function converges in time, the corresponding spatiotempor…
