Multi-Directional Periodic Driving of a Two-Level System beyond Floquet Formalism
Michael Warnock, David A. Hague, Vesna F. Mitrovic
In this manuscript, we introduce an exact expression for the response of a semi-classical two-level quantum system subject to arbitrary periodic driving. Determining the transition…
