Effects of the Spatial Structure of the Field Mode on the Internal Dynamics of the Jaynes-Cummings Model

We investigate the effects of the spatial structure of a single field mode on the internal dynamics of a two-level atom. The atom is supposed to cross a cylindrical cavity along its axis with a speed high enough to allow neglect of any effect of the interaction with the field on the atomic translational degrees of freedom. A finite detuning is supposed to exist between the atom and the field and its effects on the state of the atom at the exit from the cavity is considered. We show that if the detuning is modulated synchronously with the field mode structure the dynamics is again exactly soluble. A perturbative solution is given for the case of fixed detuning.
