ABSTRACT

For investigation of entanglement and thermodynamic properties of three coupled atoms the Dicke model is considered in the dispersive limit. Two qualitatively different regions differing in the sign of the effective coupling constant are shown. The vacuum induced Stark shift modifies strongly the physical results in these regions. In the region of negative coupling constant entanglement is more prominent: it is displayed in a wider range of temperature and atomic transition frequencies. Also the critical temperatures and the atomic transition frequencies corresponding to vanishing of entanglement are studied. More... »
