Entanglement between two atoms in an overdamped cavity injected with squeezed vacuum

The degree generation of entanglement between a pair of two level atoms embedded in a bad cavity injected with a squeezed vacuum was analyzed. It was observed that the degree of entanglement between the two atoms depends on the number of mean photons, the strength of two photon correlations of the squeezed vacuum, the cavity induced decay rate of atoms and the atomic separation. It was also observed that the atomic separation was much smaller than the resonant wavelength. It was found that the cavity mode response to the reservoir was much faster than that produced by interactions with the atoms. The result shows that the photons emitted by the atoms could not react back with the atoms.
