Outline of Final Research Achievements |
Periodically driven systems thermally isolated from the environment exhibit remarkable properties that are not easily realized in equilibrium systems. However, the system will ultimately heat up to a high temperature state, which is disordered and featureless. It is not only a practically important problem but a theoretical challenge to understand how fast the heating occurs. This is a typical problem of nonequilibrium statistical physics. We have shown that the heating becomes exponentially slow in the high frequency regime. Moreover, we studied the effect of the coupling to a thermal environment.
