| Abstract: | An exact analytical expression is found for the density matrix of a system composed of a photon mode and two two-level dipole-dipole interacting atoms in a cavity with losses. The behavior of the atom-atom entanglement has been investigated on the basis of the Peres-Horodecki criterion. |
