Avalanches and many-body resonances in many-body localized systems

A Morningstar, L Colmenarez, V Khemani, DJ Luitz… - Physical Review B, 2022 - APS
We numerically study both the avalanche instability and many-body resonances in strongly
disordered spin chains exhibiting many-body localization (MBL). Finite-size systems behave …

W Morong, F Liu, P Becker, KS Collins, L Feng… - Nature, 2021 - nature.com
Thermalization is a ubiquitous process of statistical physics, in which a physical system
reaches an equilibrium state that is defined by a few global properties such as temperature …

Challenges to observation of many-body localization

P Sierant, J Zakrzewski - Physical Review B, 2022 - APS
We study time dynamics of 1D disordered Heisenberg spin-1/2 chains focusing on a regime
of large system sizes and a long-time evolution. This regime is relevant for observation of …

Slow delocalization of particles in many-body localized phases

M Kiefer-Emmanouilidis, R Unanyan, M Fleischhauer… - Physical Review B, 2021 - APS
We have recently shown that the logarithmic growth of the entanglement entropy following a
quantum quench in a many-body localized phase is accompanied by a slow growth of the …

Critical properties of the Anderson transition on random graphs: Two-parameter scaling theory, Kosterlitz-Thouless type flow, and many-body localization

I García-Mata, J Martin, O Giraud, B Georgeot… - Physical Review B, 2022 - APS
The Anderson transition in random graphs has raised great interest, partly out of the hope
that its analogy with the many-body localization (MBL) transition might lead to a better …

Non-Abelian symmetry can increase entanglement entropy

S Majidy, A Lasek, DA Huse, N Yunger Halpern - Physical Review B, 2023 - APS
The pillars of quantum theory include entanglement and operators' failure to commute. The
Page curve quantifies the bipartite entanglement of a many-body system in a random pure …

Finite-size scaling analysis of the many-body localization transition in quasiperiodic spin chains

AS Aramthottil, T Chanda, P Sierant, J Zakrzewski - Physical Review B, 2021 - APS
We analyze the finite-size scaling of the average gap ratio and the entanglement entropy
across the many-body localization (MBL) transition in one dimensional Heisenberg spin …

Coexistence of localization and transport in many-body two-dimensional Aubry-André models

A Štrkalj, EVH Doggen, C Castelnovo - Physical Review B, 2022 - APS
Whether disordered and quasiperiodic many-body quantum systems host a long-lived
localized phase in the thermodynamic limit has been the subject of intense recent debate …

Local integrals of motion and the quasiperiodic many-body localization transition

H Singh, B Ware, R Vasseur, S Gopalakrishnan - Physical Review B, 2021 - APS
We study the many-body localization (MBL) transition for interacting fermions subject to
quasiperiodic potentials by constructing the local integrals of motion (LIOMs) in the MBL …
