Beyond the imbalance: site-resolved dynamics probing resonances in many-body localization
Asmi Haldar, Thibault Scoquart, Fabien Alet +1
We explore the limitations of using imbalance dynamics as a diagnostic tool for many-body localization (MBL) and show that spatial averaging can mask important microscopic features…
Long-range resonances in quasiperiodic many-body localization
Ashirbad Padhan, Jeanne Colbois, Fabien Alet +1
We investigate long-range resonances in quasiperiodic many-body localized (MBL) systems. Focusing on the Heisenberg chain in a deterministic Aubry-André potential, we complement st…
Large deviations in the many-body localization transition: The case of the random-field XXZ chain
Greivin Alfaro Miranda, Fabien Alet, Giulio Biroli +3
The effect of rare system-wide resonances in the many-body localization (MBL) transition has recently attracted significant attention. They are expected to play a prominent role in…
Cat states carrying long-range correlations in the many-body localized phase
Nicolas Laflorencie, Jeanne Colbois, Fabien Alet
Despite considerable efforts over the last decade, the high-energy phase diagram of the random-field Heisenberg chain still eludes our understanding, in particular the nature of th…
Statistics of systemwide correlations in the random-field XXZ chain: Importance of rare events in the many-body localized phase
Jeanne Colbois, Fabien Alet, Nicolas Laflorencie
Motivated by recent debates around the many-body localization (MBL) problem, and in particular its stability against systemwide resonances, we investigate long-distance spin-spin c…
Interaction-Driven Instabilities in the Random-Field XXZ Chain
Jeanne Colbois, Fabien Alet, Nicolas Laflorencie
Despite enormous efforts devoted to the study of the many-body localization (MBL) phenomenon, the nature of the high-energy behavior of the Heisenberg spin chain in a strong random…
