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 chaos and thermalization in isolated systems of interacting particles

F Borgonovi, FM Izrailev, LF Santos, VG Zelevinsky - Physics Reports, 2016 - Elsevier

the time scales involved in the relaxation process of isolated quantum systems that have …

Off-diagonal matrix elements of local operators in many-body quantum systems

W Beugeling, R Moessner, M Haque - Physical Review E, 2015 - APS
In the time evolution of isolated quantum systems out of equilibrium, local observables
generally relax to a long-time asymptotic value, governed by the expectation values …

Dynamics at the many-body localization transition

EJ Torres-Herrera, LF Santos - Physical Review B, 2015 - APS
The isolated one-dimensional Heisenberg model with static random magnetic fields has
become paradigmatic for the analysis of many-body localization. Here, we study the …

Spread complexity evolution in quenched interacting quantum systems

M Gautam, K Pal, K Pal, A Gill, N Jaiswal, T Sarkar - Physical Review B, 2024 - APS
We analyze time evolution of spread complexity (SC) in an isolated interacting quantum
many-body system when it is subjected to a sudden quench. Characteristics features of the …

Scrambling the spectral form factor: unitarity constraints and exact results

A Del Campo, J Molina-Vilaplana, J Sonner - Physical Review D, 2017 - APS
Quantum speed limits set an upper bound to the rate at which a quantum system can evolve,
and as such can be used to analyze the scrambling of information. To this end, we consider …

Relaxation and thermalization in the one-dimensional Bose-Hubbard model: A case study for the interaction quantum quench from the atomic limit
