The Statistic Properties of a Two-Photon Jaynes-Cummings Model in an External Field
Xia Lixin, Zeng Gao-jian
Abstract
Studied a two-photon Jaynes-Cummings model in an external field. The interaction between the atom system and the external field is regarded as a perturbation. Using the perturbation theory, we obtain its wave functions up to the first-order, and discuss the photon number distribution of the cavity field and the population inversion of the atom in the system.
