Nonclassical Properties for Two Coupled N-Two-Level Atom and a Single Two-Level Atom Under an External Magnetic Field
We study the interaction between a single two-level atom and N two-level atoms under the effect of a uniform magnetic field. The exact solution is obtained and the expectation value of the time-dependent quantum ...

The interaction between a single two-level atom and the combination of a frequency converter and the sub-harmonic generation
The problem of a time-dependent quantum system, which consists of coupled sub-harmonic generation with the parametric down conversion injected within a single cavity containing an atom, is considered. The prob...

Some statistical properties for a moving three-level atom in interaction with a bimodal cavity field
In this paper we consider the problem of the interaction between a three-level atom and a quantized bimodal cavity field. The coupling parameter between the atom and the field is taken to be time-dependent by ...

Sensitive Response of the Quantum Entropies to Jaynes-Cummings Model in Presence of a Second Harmonic Generation
The behavior of a modified Jaynes-Cummings Hamiltonian model (two-level atom in interaction with an electromagnetic field) in the presence of degenerate parametric amplification is introduced. We have examined...
