Abstract

Near-resonant ac-drive acting on a two-level system induces the Rabi oscillations of the level occupations. It is shown that additional weak drive properly frequency-detuned from the primary drive causes a resonant response. This response manifests itself in the emergence of the envelope of the oscillations. At resonance, the inverse period of the envelope is proportional to the amplitude of the weak drive. The resonant condition reads: difference of frequencies between the two drives is equal to the ac-splitting of quasilevels in the field of the strong drive. Technically, the resonance can be inferred from the analogy between the equations for the time-evolution of the spin projection and the Mathieu equation, which describes e.g. the parametric resonance.
