报告摘要:
Open
quantum systems provide a natural platform for exploring nonequilibrium
phenomena arising from the interplay between coherent evolution and
environmental dissipation. In this talk, I will present several recent
studies on nonequilibrium dynamics in open quantum systems. Firstly, I
will discuss dissipation-induced extended-localized transitions, where
dissipation drives systems with mobility edges into states dominated by
either extended or localized components, largely independent of the
initial state. Secondly, I will introduce a general strategy for
realizing the Mpemba effect in open quantum systems, where engineered
dissipation gives rise to anomalous relaxation, allowing a hotter state
to relax faster than a colder one. Finally, I will show that
time-averaged local translational contrast provides a dynamical
characterization of topological phase transitions that applies to both
open and closed systems. These results demonstrate that dissipation is
not merely a source of decoherence, but also a powerful tool for
controlling dynamics, revealing nonequilibrium phenomena, and
characterizing emergent phases in open quantum systems.
