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 thermalization through entanglement in an isolated many-body system

AM Kaufman, ME Tai, A Lukin, M Rispoli, R Schittko… - Science, 2016 - science.org
Statistical mechanics relies on the maximization of entropy in a system at thermal
equilibrium. However, an isolated quantum many-body system initialized in a pure state …

Probing quantum scars and weak ergodicity breaking through quantum complexity

B Bhattacharjee, S Sur, P Nandy - Physical Review B, 2022 - APS
Scar states are special many-body eigenstates that weakly violate the eigenstate
thermalization hypothesis (ETH). Using the explicit formalism of the Lanczos algorithm …

Ergodic dynamics and thermalization in an isolated quantum system

C Neill, P Roushan, M Fang, Y Chen, M Kolodrubetz… - Nature Physics, 2016 - nature.com
Statistical mechanics is founded on the assumption that all accessible configurations of a
system are equally likely. This requires dynamics that explore all states over time, known as …

Entanglement transitions from holographic random tensor networks

R Vasseur, AC Potter, YZ You, AWW Ludwig - Physical Review B, 2019 - APS

entanglement features. An example of such an “entanglement phase transition” is provided …

Entanglement dynamics after quantum quenches in generic integrable systems

V Alba, P Calabrese - SciPost Physics, 2018 - scipost.org
The time evolution of the entanglement entropy in non-equilibrium quantum systems
provides crucial information about the structure of the time-dependent state. For quantum …

Does a single eigenstate encode the full Hamiltonian?

JR Garrison, T Grover - Physical Review X, 2018 - APS
The eigenstate thermalization hypothesis (ETH) posits that the reduced density matrix for a
subsystem corresponding to an excited eigenstate is “thermal.” Here we expound on this …

Sachdev-Ye-Kitaev model and thermalization on the boundary of many-body localized fermionic symmetry-protected topological states

YZ You, AWW Ludwig, C Xu - Physical Review B, 2017 - APS
