Abstract
It is widely recognized that finite temperatures degrade quantum coherence and can induce thermalization. Here, we study the effect of finite temperature on a kicked Tonks-Girardeau gas, which is known to exhibit many-body dynamical localization and delocalization under periodic and quasiperiodic kicks, respectively. We find that many-body dynamical localization persists at finite—and even high—temperatures, although the coherence of the localized state is further degraded. In particular, we demonstrate a modified effective thermalization of the localized state by considering the initial temperature. Moreover, we show a many-body dynamical localization transition at intermediate temperature. Our work extends the study of many-body dynamical localization and delocalization to the finite-temperature regime, providing guidance for cold-atom experiments, particularly in the strongly interacting regime.
