Description
In this talk, we shall study periodic dynamics of a class of closed integrable quantum systems. We shall show that a periodic drive may lead to controlled generation of states with non-area and non-volume law entanglement. In addition, we unravel a dynamical transition in such systems separating regimes with distinct power law decays of all correlation functions to their steady state (GGE) value. We show that this transition occurs due to change in topology of the system's Floquet spectrum and discuss experiments which can test our theory.
