Entanglement between atoms succesively passing the cavity with thermal field

In the present paper the entanglement dynamics of two atoms succesively passing the one-atom maser cavity with finite temperature has been considered. The influence of the initial atomic coherence and intensity of the thermal cavity field on the degree of the atomic entanglement has been investigated. It has been shown that the interaction between atoms and cavity low-intensity thermal field leads to entanglement for all initial atomic states and the initial atomic coherence leads to decreasing of the degree of the entanglement.
