Description
Rare system-wide resonances are expected to play a prominent role in driving the many-body localization (MBL) transition and dictating the stability of the MBL phase. In this talk, we introduce a novel theoretical framework based on an analogy with mean-field disordered glassy systems to properly account for the statistical weight of these resonant configurations. Utilizing this framework, we generate biased disorder realizations to investigate the structural origin of long-range resonances in the Hilbert space. Our results demonstrate that their formation is fundamentally driven by the emergence of extended regions with anomalously weak disorder in real space.
