摘       要：This talk is structured in two parts. We begin by introducing key concepts in non-Hermitian physics, with a special focus on the non-Hermitian skin effect (NHSE)—a hallmark phenomenon rooted in nonreciprocity that leads to the exponential localization of bulk states at boundaries. After reviewing its dynamical consequences, we present our recent work on nonreciprocity-enriched phases in open quantum systems. Although nonreciprocity and the NHSE are known to drive unconventional dynamics, their influence on steady-state phases has remained elusive. We demonstrate that the interplay between nonreciprocity and boundary conditions fundamentally reshapes the phase landscape, giving rise to novel nonequilibrium states with distinct spatiotemporal order.
