MULTIPHOTON INTERACTION OF A TWO-LEVEL ATOM WITH A LARGE PERIOD QUANTIZED STANDING WAVE FIELD BEYOND THE RAMAN-NATH REGIME

A model that describes the multiphoton interaction of a two-level atom with a large period quantized standing wave field beyond the Raman-Nath regime is solved exactly by the Wei-Norman's operator factorization method, and the momentum distribution of the atom is discussed. We also investigate the dynamics of the atomic population inversion and field second-order correlation function. They exhibit very remarkable behavior due to the inclusion of atomic translational motion.
