The dynamics of the two level and three level cascade atoms undergoing two photon transistions are investigated in the cavity filled with Kerr like medium. The problems are solved exactly in the presence of an initial coherent state field using EHA with the Stark-shift parameters and THA, respectively. Comparing the numerical results of atomic population inversion, photon probability distribution, bunching and antibunching characteristics and squeezing, we have shown that the two approaches exhibit similar...

The dynamics of the two level and three level cascade atoms undergoing two photon transistions are investigated in the cavity filled with Kerr like medium. The problems are solved exactly in the presence of an initial coherent state field using EHA with the Stark-shift parameters and THA, respectively. Comparing the numerical results of atomic population inversion, photon probability distribution, bunching and antibunching characteristics and squeezing, we have shown that the two approaches exhibit similar behaviors with a little difference under the condition of nonlinear field.

The time dependent properties of the atomic population inversion and atomic dipole squeeze in the nondegenerate two photon Tavis Cummings model in two mode vacuum field are studied by means of quantum theory.

The wave-function of the system of single-mode field interacting with N-type four-level atom is solved exactly, and the time-evolution of atomic particle's occupancy is analyzed by means of numerical method. The N-type four-level atom is about equal to the two-level atom whose every level has double-skin fine structure, it could degenerate into V-type or Λ-type three-level atom even into simple two-level atom under some conditions. The results of the studies indicate that the time-evolution of atomic particle's...
