Abstract:
The nonequilibrium dynamics of quantum many-body systems have attracted growing attention due to various intriguing phenomena absent in equilibrium physics. One famous example is the quantum Mpemba effect, where the symmetry is restored faster under a symmetric quench from a more asymmetric initial state. In this talk, we investigate symmetry restoration dynamics and the associated quantum Mpemba effects in both quantum chaotic and many-body localization systems using theoretical tools such as random quantum circuits and the effective models for MBL. We study symmetry restoration behaviors for different initial states and internal symmetries and present a unified framework to understand these diverse phenomena through the lens of quantum thermalization.
