Statistics of work distribution in periodically driven closed quantum systems

Abstract

We study the statistics of the work distribution P(w)P(w) in a dd-dimensional closed quantum system with linear dimension LL subjected to a periodic drive with frequency ω0\omega_0. We show that after an integer number of periods of the drive, the corresponding rate function I(w)=ln[P(w)]/LdI(w)= -\ln[P(w)]/L^d satisfies an universal lower bound I(0)ndI(0)\ge n_d and has a zero at w=Qw=Q, where ndn_d and QQ are the defect density and residual energy generated during the drive. We supplement our results by calculating I(w)I(w) for a class of dd-dimensional integrable models and show that it has oscillatory dependence on ω0\omega_0 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.
