Abstract

An exact solution of the problem of two two-level atoms with nondegenerate two-photon transitions and intensitydependent coupling interacting with two-mode radiation field is presented. Asymptotic solution for system state vector is obtained in the approximation of large initial coherent fields. The atom-field entanglement is investigated on the basis of the reduced atomic entropy dynamics. The possibility of the system being initially in a pure disentangled state to revive into this state during the evolution process is shown. Conditions and times of disentanglement are derived.
