Two Decades of Debates on Many-Body Localization: Insights Gained and New Challenges
Extending Anderson localization to interacting many-body systems is a very challenging question. Despite two decades of intense research, the nature of many-body localization (MBL) remains unclear. In this talk, I will introduce the MBL problem through simple disordered interacting spin models. After reviewing key results, developments, and controversies, I will present our recent findings. First, I will discuss the role of rare events and many-body resonances, particularly their potential to destabilize MBL [1-3]. If time permits, I will also present unpublished results on out-of-equilibrium dynamics [4] that could clarify past numerical controversies and inspire new experiments.
