Abstract

The exact wave function and asymptotic expressions for the system state vectors under strong initial coherent fields are found in the work for the two-atom models with nondegenerate two-photon interaction and nondegen- erate Raman interaction. The atom-field entanglement is considered via linear entropy criterion. The system revivals to unentangled states are shown to appear for both models. The disentanglement times are derived in the work. The atom-atom entanglement induced by thermal noise is investigated for the both models.
