Statistical mechanics provides a framework for describing the physics of large, complex
many-body systems using only a few macroscopic parameters to determine the state of the …

Many-body resonances in the avalanche instability of many-body localization

H Ha, A Morningstar, DA Huse - Physical review letters, 2023 - APS
Many-body localized (MBL) systems fail to reach thermal equilibrium under their own
dynamics, even though they are interacting, nonintegrable, and in an extensively excited …

Uncovering local integrability in quantum many-body dynamics

O Shtanko, DS Wang, H Zhang, N Harle, A Seif… - arXiv preprint arXiv …, 2023 - arxiv.org
Interacting many-body quantum systems and their dynamics, while fundamental to modern
science and technology, are formidable to simulate and understand. However, by …

Emergence of fluctuating hydrodynamics in chaotic quantum systems

JF Wienand, S Karch, A Impertro, C Schweizer… - arXiv preprint arXiv …, 2023 - arxiv.org
A fundamental principle of chaotic quantum dynamics is that local subsystems eventually
approach a thermal equilibrium state. Large subsystems thermalize slower: their approach …

Cold-Atom Elevator: From Edge-State Injection to the Preparation of Fractional Chern Insulators

B Wang, M Aidelsburger, J Dalibard, A Eckardt… - Physical review …, 2024 - APS
Optical box traps offer new possibilities for quantum-gas experiments. Building on their
exquisite spatial and temporal control, we propose to engineer system-reservoir …

Similarity between a many-body quantum avalanche model and the ultrametric random matrix model

J Šuntajs, M Hopjan, W De Roeck, L Vidmar - Physical Review Research, 2024 - APS
In the field of ergodicity-breaking phases, it has been recognized that quantum avalanches
can destabilize many-body localization at a wide range of disorder strengths. This has in …

Large-deviation analysis of rare resonances for the many-body localization transition

G Biroli, AK Hartmann, M Tarzia - Physical Review B, 2024 - APS
A central theoretical issue at the core of the current research on many-body localization
(MBL) consists in characterizing the statistics of rare long-range resonances in many-body …

Many-body mobility edge in quantum sun models

K Pawlik, P Sierant, L Vidmar, J Zakrzewski - Physical Review B, 2024 - APS
The quantum sun model is an interacting model that exhibits sharp signatures of ergodicity
breaking phase transition. Here, we show that the model exhibits a many-body mobility …

Catching thermal avalanches in the disordered XXZ model

T Szołdra, P Sierant, M Lewenstein, J Zakrzewski - Physical Review B, 2024 - APS
We study the XXZ model with a random magnetic field in contact with a weakly disordered
spin chain, acting as a finite thermal bath. We revise Fermi's golden rule description of the …

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 …
