学术预告 | 广东省磁电物性分析与器件重点实验室学术讲座(第二十八期)：非厄米物理：非常规缀饰态，关联无序和相互作用效应

Recent years have witnessed considerable interest in exploring various fascinating aspects of unconventional physical phenomena in non-Hermitian systems. Non-Hermiticity is relevant for continuously monitored quantum many-body systems, which describes physics differently from the master-equation approach, where outcomes are averaged out. In this aspect, the dynamics described by non-Hermiticity is nontrivial.  One of its salient characteristics is the point-gap topology and emergence of non-Hermitian skin effect.   In this talk, I will start with an overview of non-Hermitian phenomena. Then I will present our recent investigation of non-Hermitian phenomena, including the unconventional emitter-photon dressed states resulting from the  non-Hermitian topological bath,  reentrant non-Hermitian skin effects induced by correlated disorder, and interaction-loss controlled non-Hermitian skin effects.
