Two-level dynamics: Rabi flopping in the strong coupling regime

Marco Frasca

Show affiliations


We discuss the dynamics of a two-level model in a strong coupling regime through the analysis of the probability amplitudes. It is seen that the theory recovers Rabi flopping also for strong coupling. Population trapping can occur and a decay constant for the excited state is also computed. Then, spontaneous emission can be made to disappear or, otherwise, the emitted photon turns out to have a frequency being an odd harmonic of the frequency of the perturbation.
