报告内容：

In this talk, I will present our recent theoretical and experimental collaborative progress on localization physics, focusing on three main directions: (1) Critical phases: We report the discovery of many-body critical phases, propose experimental protocols to probe critical behavior, and, in collaboration with experiments, measure the full dynamical properties of a Fibonacci chain exhibiting critical structures.(2) Mobility edges: We show that, in systems with a mobility edge, dissipation can serve as a novel mechanism to induce extended-to-localized transitions. We further identify a new type of mobility edge and experimentally probe five distinct classes of localized phases, including those featuring mobility edges and critical phases. (3) Localization transitions: We propose a framework to understand localization transitions in terms of dynamical translation symmetry breaking.
