报告摘要：

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 non-Hermitian setup via Floquet engineering and disorder effects due to their interplay with point-gap topology.
