The influence of dynamical Stark shift on the entanglement between two atoms prepared in initial $W$-like states in Tavis–Cummings model with degenerate two-photon transitions has been investigated. The results show that effect of sudden death of entanglement the effect can be weakened for some initial states with taking into account the Stark shift.
Keywords: two-atom model, degenerate two-photon transitions, Stark shift, sudden death of entanglement.
