Statistics of work distribution in periodically driven closed quantum systems
Abstract
We study the statistics of the work distribution in a dimensional closed quantum system with linear dimension subjected to a periodic drive with frequency . We show that after an integer number of periods of the drive, the corresponding rate function satisfies an universal lower bound and has a zero at , where and are the defect density and residual energy generated during the drive. We supplement our results by calculating for a class of -dimensional integrable models and show that it has oscillatory dependence on originating from Stuckelberg interference generated during multiple passage through intermediate quantum critical points or regions during the drive. We suggest experiments to test our theory.
