[HTML][HTML] Many-body localization: An introduction and selected topics

F Alet, N Laflorencie - Comptes Rendus Physique, 2018 - Elsevier
What happens in an isolated quantum system when both disorder and interactions are
present? Over the recent years, the picture of a non-thermalizing phase of matter, the many …

Time-crystalline eigenstate order on a quantum processor

X Mi, M Ippoliti, C Quintana, A Greene, Z Chen, J Gross… - Nature, 2022 - nature.com
Quantum many-body systems display rich phase structure in their low-temperature
equilibrium states. However, much of nature is not in thermal equilibrium. Remarkably, it was …

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 …

Operator spreading and the emergence of dissipative hydrodynamics under unitary evolution with conservation laws

V Khemani, A Vishwanath, DA Huse - Physical Review X, 2018 - APS
We study the scrambling of local quantum information in chaotic many-body systems in the
presence of a locally conserved quantity like charge or energy that moves diffusively. The …

Quantum chaos challenges many-body localization

J Šuntajs, J Bonča, T Prosen, L Vidmar - Physical Review E, 2020 - APS
Characterizing states of matter through the lens of their ergodic properties is a fascinating
new direction of research. In the quantum realm, the many-body localization (MBL) was …

Discrete time crystals: Rigidity, criticality, and realizations

NY Yao, AC Potter, ID Potirniche, A Vishwanath - Physical review letters, 2017 - APS

can occur in periodically driven, Floquet systems with discrete time-translation symmetry …

Phase structure of driven quantum systems

V Khemani, A Lazarides, R Moessner, SL Sondhi - Physical review letters, 2016 - APS
Clean and interacting periodically driven systems are believed to exhibit a single, trivial
“infinite-temperature” Floquet-ergodic phase. In contrast, here we show that their disordered …
