Two-photon atomic transitions with a squeezed cavity field and Stark shift

Entanglement Transfer from Two-Mode Squeezed Vacuum State Field to Two Spatially Separated Atoms in Two-Photon Processes

“…For simplicity, we consider on-resonance interaction, i.e., ω 0 = ω eg = 2ω, whereas the intermediate transition frequencies ω ei = ω + ∆ and ω ig = ω − ∆. By diagonalizing H 1,A in the basis {|1 ≡ |e, n , |2 ≡ |g, n + 2 }, the time-evolution operator in the interaction picture can be obtained, [13] U…”

“…[11−13] Some authors have studied the influence of the Stark shift term on atomic inversion and dipole squeezing in two-photon processes. [12,13] Besides, much attention has been focused on the entanglement of field and atom in the two-photon JCM. In this letter, we will investigate the effect of the Stark shift on the entanglement transfer from two-mode squeezed vacuum state field to two remote atoms in two-photon processes.…”

Fluorescence and absorption spectra for a multi-photon Jaynes–Cummings in the presence of nonlinearities and stark shift

“…In fact, the interaction between a two-level atom and the radiation field is a quantum optical problem that lies at the heart of many problems in laser physics and quantum optics [2][3][4]. Much of theoretical work on the atomic emission spectra is based on the two-photon JCM [5][6][7][8][9][10], Nasreen and Razmi [8] studied the emission spectrum of the atom and the cavity field spectrum, with concentration on the effects of the Stark shift on the spectrum. Ashraf [10] studied the cavity field spectra for various initial fields of the non-degenerate two-photon JCM and showed that a two-peak structure appears for initial coherent and thermal fields.…”

Effect of stark shift on three-level atom interacting with a correlated two-mode of non-linear coherent state

“…Its effect has been studied on some phenomena in different quantum systems. The problem of two-photon atomic transitions in the presence of a squeezed cavity field and SS has been studied where ESS on some quantities has been discussed [12].…”
