Dynamics and transport at the threshold of many-body localization

S Gopalakrishnan, SA Parameswaran - Physics Reports, 2020 - Elsevier
Many-body localization (MBL) describes a class of systems that do not approach thermal
equilibrium under their intrinsic dynamics; MBL and conventional thermalizing systems form …

Renormalization-group study of the many-body localization transition in one dimension

A Morningstar, DA Huse - Physical Review B, 2019 - APS
Using a new approximate strong-randomness renormalization group (RG), we study the
many-body localized (MBL) phase and phase transition in one-dimensional quantum …

Eigenstate thermalization in dual-unitary quantum circuits: Asymptotics of spectral functions

F Fritzsch, T Prosen - Physical Review E, 2021 - APS
The eigenstate thermalization hypothesis provides to date the most successful description of
thermalization in isolated quantum systems by conjecturing statistical properties of matrix …

Subdiffusive Thouless time scaling in the Anderson model on random regular graphs

L Colmenarez, DJ Luitz, IM Khaymovich, G De Tomasi - Physical Review B, 2022 - APS
The scaling of the Thouless time with system size is of fundamental importance to
characterize dynamical properties in quantum systems. In this work, we study the scaling of …

Probability transport on the Fock space of a disordered quantum spin chain

I Creed, DE Logan, S Roy - Physical Review B, 2023 - APS
Within the broad theme of understanding the dynamics of disordered quantum many-body
systems, one of the simplest questions one can ask is, given an initial state, how does it …

Ergodic inclusions in many-body localized systems

L Colmenarez, DJ Luitz, W De Roeck - Physical Review B, 2024 - APS
We investigate the effect of ergodic inclusions in putative many-body localized systems. We
consider the random field Heisenberg chain, which is many-body localized at strong …

Eigenstate Correlations, the Eigenstate Thermalization Hypothesis, and Quantum Information Dynamics in Chaotic Many-Body Quantum Systems

D Hahn, DJ Luitz, JT Chalker - Physical Review X, 2024 - APS
We consider the statistical properties of eigenstates of the time-evolution operator in chaotic
many-body quantum systems. Our focus is on correlations between eigenstates that are …

Apparent slow dynamics in the ergodic phase of a driven many-body localized system without extensive conserved quantities

TLM Lezama, S Bera, JH Bardarson - Physical Review B, 2019 - APS
We numerically study the dynamics on the ergodic side of the many-body localization
transition in a periodically driven Floquet model with no global conservation laws. We …

Multiscale entanglement clusters at the many-body localization phase transition

L Herviou, S Bera, JH Bardarson - Physical Review B, 2019 - APS
We numerically study the formation of entanglement clusters across the many-body
localization transition. We observe a crossover from strong many-body entanglement in the …

Percolation in Fock space as a proxy for many-body localization

S Roy, JT Chalker, DE Logan - Physical Review B, 2019 - APS
We study classical percolation models in Fock space as proxies for the quantum many-body
localization (MBL) transition. Percolation rules are defined for two models of disordered …
