Influence of field dynamics on Rabi oscillations: Beyond the standard semiclassical Jaynes—Cummings model
A. Cives-esclop, Alfredo Luis, Luis Lorenzo Sánchez-Soto · Journal of Modern Optics · 1999
The semiclassical interaction of a two-level atom with a singlemode field, taking into account the atomic reaction onto the field, is considered. Analytical expressions for the field and atomic dynamics are found. An expansion of this solution in terms of the inverse of the field intensity is performed. To zeroth order, the classical Rabi solution is recovered, while first-order corrections give rise to a slow modulation of the atomic dipole, in agreement with a fully quantum model. The evolution of the atomic dipole is studied in the framework of the reduced Q function, both in the semiclassical and quantum regimes. PACS 42.50.Dv — 03.65.-w.
