Atomic dipole squeezing in two-photon processes in the presence of Stark shift in an ideal cavity

Dynamics and maintenance of bipartite entanglement via the Stark shift effect inside dissipative reservoirs

“…In direct relation to the present work, we mention that the interaction between a singlemode cavity and an effective two level atom via twophoton transition has been investigated in the presence of Stark shift in [32][33][34]. Also, many authors have suggested helpful proposals around the influence of Stark shift in the evolution of entanglement in atomic systems coupled to a quantized cavity field [35][36][37][38].…”

Unified Approach for the Kerr Effect, Stark Effect and Doppler Effect in the Atom-Field Interaction

“…Let us consider a two-level atom interacting with a single mode quantized field including the Kerr effect, Stark effect and Doppler effect. In the dipole and rotating wave approximation, the Hamiltonian of the system is' 5,7,10 ' (h = 1) H = ^-+ lu 0 a 3 + wa^a + q(a^a) 2 + ata(/3a|T><T| + MX1I)…”

“…3 ' 4 ' The JCM is extended to many directions. Among them, important generalizations are the JCM including the Kerr effect,' 5 ' 6 ' the Stark effect' 7,8 ' and the Doppler effect' 9 -10 ' respectively. We have solved the JCM including the Doppler effect exactly by the unitary transformation technique.'…”
