Abstract

In this paper we have investigated the atom-atom entanglement for degenerate two-photon Tavis-Cummings model with taking into account Stark shift and initial atomic coherence. Considering different initial coherent states we have derived that the atom-atom entanglement can be greatly increased or decreased due to the presence of the Stark shift. In addition, we have derived that the entanglement sudden death effect vanishes due to the presence of Stark shift for some initial states.
