Body-assisted van der Waals interaction between excited atoms
Hassan Safari, Mohammad Reza Karimpour
We present a formula for the body-assisted van der Waals interaction potential between two atoms, one or both being prepared in an excited energy eigenstate. The presence of arbitr…
Algebraic and group treatments to nonlinear displaced number states and their nonclassicality features
N. Asili Firouzabadi, M. K. Tavassoly, M. J. Faghihi
Recently, nonlinear displaced number states (NDNSs) have been \emph{manually} introduced, in which the deformation function has been artificially added to the well-known dis…
Entanglement criteria of two two-level atoms interacting with two coupled modes
H. R. Baghshahi, M. J. Faghihi, M. K. Tavassoly
In this paper, we study the interaction between two two-level atoms and two coupled modes of a quantized radiation field in the form of parametric frequency converter injecting wit…
Dynamics of entanglement of a three-level atom in motion interacting with two coupled modes including parametric down conversion
M. J. Faghihi, M. K. Tavassoly, M. Hatami
In this paper, a model by which we study the interaction between a motional three-level atom and two-mode field injected simultaneously in a bichromatic cavity is considered; the t…
Tripartite entanglement dynamics and entropic squeezing of a three-level atom interacting with a bimodal cavity field
M. J. Faghihi, M. K. Tavassoly, M. Bagheri Harouni
In this paper, we study the interaction between a -type three-level atom and two quantized electromagnetic fields which are simultaneously injected in a bichromatic cavity surro…
Quantum entanglement and position-momentum entropic squeezing of a moving Lambda-type three-level atom interacting with a single-mode quantized field with intensity-dependent coupling
M. J. Faghihi, M. K. Tavassoly
In this paper, we study the interaction between a moving -type three-level atom and a single-mode cavity field in the presence of intensity-dependent atom-field coupling. After…
