Multiphoton Raman transitions and Rabi oscillations in driven spin systems
Multiphoton Raman transitions and Rabi oscillations in driven spin systems
In the framework of the nonsecular perturbation theory based on the Bogoliubov averaging method, the coherent dynamics of multiphoton Raman transitions in a two-level spin system driven by an amplitude-modulated microwave field is studied. Closed-form expressions for the Rabi frequencies of these transitions are obtained beyond the rotating-wave approximation for …
