Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems

C Gogolin, J Eisert - Reports on Progress in Physics, 2016 - iopscience.iop.org
We review selected advances in the theoretical understanding of complex quantum many-
body systems with regard to emergent notions of quantum statistical mechanics. We cover …

Quantum quench in the sine-Gordon model

B Bertini, D Schuricht, FHL Essler - Journal of Statistical …, 2014 - iopscience.iop.org
We consider the time evolution in the repulsive sine-Gordon quantum field theory after the
system is prepared in a particular class of initial states. We focus on the time dependence of …

On conservation laws, relaxation and pre-relaxation after a quantum quench

M Fagotti - Journal of Statistical Mechanics: Theory and …, 2014 - iopscience.iop.org
We consider the time evolution following a quantum quench in spin-1/2 chains. It is well
known that local conservation laws constrain the dynamics and, eventually, the stationary …

Time-dependent generalized Gibbs ensembles in open quantum systems

F Lange, Z Lenarčič, A Rosch - Physical Review B, 2018 - APS
Generalized Gibbs ensembles have been used as powerful tools to describe the steady
state of integrable many-particle quantum systems after a sudden change of the …
