Many-body localization (MBL) is an example of a dynamical phase of matter that avoids thermalization. While MBL phase is robust to weak local perturbations, the fate of an MBL system coupled to a thermalizing quantum system that represents a “heat bath” is an open question that is actively investigated theoretically and experimentally. In this work we consider the stability of an Anderson insulator with a finite density of particles interacting with a single mobile impurity — a small quantum… Expand

Localization of a mobile impurity interacting with an Anderson insulator
Thermalizing and localized many-body quantum systems present two distinct dynamical phases of matter. Recently, the fate of a localized system coupled to a thermalizing system viewed as a quantumExpand
Destruction of Localization by Thermal Inclusions: Anomalous Transport and Griffiths Effects in the Anderson and Andr\'e-Aubry-Harper Models
We discuss and compare two recently proposed toy models for anomalous transport and Griffiths effects in random systems near the Many-Body Localization transitions: the random dephasing model, whichExpand

TLDR
The significance for proposed atomic experiments is that local measurements will show a large but nonthermal entropy in the many-body localized state, which develops slowly over a diverging time scale as in glassy systems. Expand
Signatures of Many-Body Localization in a Controlled Open Quantum System
In the presence of disorder, an interacting closed quantum system can undergo many-body localization (MBL) and fail to thermalize. However, over long times, even weak couplings to any thermalExpand
Many-body localization in the presence of a small bath
In the presence of strong disorder and weak interactions, closed quantum systems can enter a many-body localized phase where the system does not conduct, does not equilibrate even for arbitrarilyExpand
Exploration of the stability of many-body localization in d>1
Recent work by De Roeck et al. [Phys. Rev. B 95, 155129 (2017)] has argued that many-body localization (MBL) is unstable in two and higher dimensions due to a thermalization avalanche triggered byExpand
Many-Body Delocalization in the Presence of a Quantum Bath
Closed generic quantum many-body systems may fail to thermalize under certain conditions even after long times, a phenomenon called many-body localization (MBL). Numerous studies have left no doubtExpand
Theory of the many-body localization transition in one dimensional systems
We formulate a theory of the many-body localization transition based on a novel real space renormalization group (RG) approach. The results of this theory are corroborated and intuitively explainedExpand
Signatures of the many-body localized regime in two dimensions
Lessons from Anderson localization highlight the importance of the dimensionality of real space for localization due to disorder. More recently, studies of many-body localization have focused on theExpand
Metal–insulator transition in a weakly interacting many-electron system with localized single-particle states
Abstract We consider low-temperature behavior of weakly interacting electrons in disordered conductors in the regime when all single-particle eigenstates are localized by the quenched disorder. WeExpand
Exploration of the stability of many-body localized systems in the presence of a small bath
When pushed out of equilibrium, generic interacting quantum systems equilibrate locally and are expected to evolve towards a locally thermal description despite their unitary time evolution. SystemsExpand
