Periodic Steady Regime and Interference in a Periodically Driven Quantum System
Periodic Steady Regime and Interference in a Periodically Driven Quantum System
We study the coherent dynamics of a quantum many-body system subject to a time-periodic driving. We argue that in many cases, destructive interference in time makes most of the quantum averages time-periodic, after an initial transient. We discuss in detail the case of a quantum Ising chain periodically driven across …
