From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics

L D'Alessio, Y Kafri, A Polkovnikov, M Rigol - Advances in Physics, 2016 - Taylor & Francis
This review gives a pedagogical introduction to the eigenstate thermalization hypothesis
(ETH), its basis, and its implications to statistical mechanics and thermodynamics. In the first …

Quantum chaos and thermalization in isolated systems of interacting particles

F Borgonovi, FM Izrailev, LF Santos, VG Zelevinsky - Physics Reports, 2016 - Elsevier
This review is devoted to the problem of thermalization in a small isolated conglomerate of
interacting constituents. A variety of physically important systems of intensive current interest …

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 …

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

S Sorg, L Vidmar, L Pollet, F Heidrich-Meisner - Physical Review A, 2014 - APS
Motivated by recent experiments, we study the relaxation dynamics and thermalization in the
one-dimensional Bose-Hubbard model induced by a global interaction quench. Specifically …

Validity of the GGE for quantum quenches from interacting to noninteracting models

S Sotiriadis, P Calabrese - Journal of Statistical Mechanics …, 2014 - iopscience.iop.org
In the majority of analytical verifications of the conjecture that the Generalized Gibbs
Ensemble (GGE) describes the large time asymptotics of local observables in quantum …

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 …

Extended nonergodic states in disordered many‐body quantum systems

EJ Torres‐Herrera, LF Santos - Annalen der Physik, 2017 - Wiley Online Library
This work supports the existence of extended nonergodic states in the intermediate region
between the chaotic (thermal) and the many‐body localized phases. These states are …

Local quenches with global effects in interacting quantum systems

EJ Torres-Herrera, LF Santos - Physical Review E, 2014 - APS
We study one-dimensional lattices of interacting spins-1 2 and show that the effects of
quenching the amplitude of a local magnetic field applied to a single site of the lattice can be …

Dynamical manifestations of quantum chaos: correlation hole and bulge

EJ Torres-Herrera, LF Santos - … Transactions of the …, 2017 - royalsocietypublishing.org
A main feature of a chaotic quantum system is a rigid spectrum where the levels do not
cross. We discuss how the presence of level repulsion in lattice many-body quantum …

Quantum quenches in the thermodynamic limit

M Rigol - Physical review letters, 2014 - APS
We introduce a linked-cluster based computational approach that allows one to study
quantum quenches in lattice systems in the thermodynamic limit. This approach is used to …
