NV center in diamond,Floquet theory

Interesting phenomena such as multiple photon transitions and coherent destruction of tunneling are observed under simultaneous excitation of the NV center electron spins in diamond by microwave and RF fields. Here, we discuss the scope of application of a rotating wave approximation (RWA) by comparing the results of numerical calculations in an RWA with the results of exact numerical calculations based on the Floquet theory.
