Many-Body Critical Phase: Extended and Nonthermal
Many-Body Critical Phase: Extended and Nonthermal
The transition between ergodic and many-body localization (MBL) phases lies at the heart of understanding quantum thermalization of many-body systems. Here, we predict a many-body critical (MBC) phase with finite-size scaling analysis in the one-dimensional extended Aubry-Andr\'e-Harper-Hubbard model, which is different from both the ergodic phase and MBL phase, implying …
