In this paper, an analytical model for the interaction between a moving Λ-type three-level atom and a two-mode radiation field is presented with two-photon transitions and in the intensity-dependent coupling regime. After specifying the initial conditions for the atom and the field, the explicit form of the state vector of the entire system is obtained via the time evolution operator. In order to study the entanglement between subsystems, atom and field, temporal behavior of the von Neumann entropy, as a measure of entanglement, is examined.
Keywords: Moving three-level atom, Two-mode field, Two-photon transition, Intensity-dependent coupling, Quantum entanglement
