Abstract: The influence of dipole-dipole interaction on the entanglement between two atoms and field in many-photon Tavis–Cummings with coherent cavity mode has been investigated. The results show that in the case of one-photon model the dipole-dipole interaction leads to the stabilization of atom-field entanglement.

Keywords: two-atom model, many-photon transitions, dipole-dipole interaction, atom-field entanglement.
