Time dynamics and entropy production to thermalization in EGOE

Abstract

Further application of embedded ensembles (EEs) is to time dynamics and entropy production in isolated finite interacting many-particle systems. Results here are useful in the study of the stability of a quantum computer against quantum chaos and in the study of issues related to statistical relaxation and thermalization in isolated finite quantum systems. It is also possible to address fidelity and Loschmidt echoes in many-particle quantum systems using EEs. Available results in these topics are briefly discussed. © 2014 Springer International Publishing Switzerland.
