Dynamics of a three level atom interacting with a detuned SU (1,1) quantum system
Starting from the interaction between a 3-level atom in the cascade configuration with an SU(1, 1) quantum system, an effective Hamiltonian for a 2-level atom with the presence of a Stark shift structure is ob...

Squeezing properties of the Kerr-down conversion system
In this paper we describe a new two-mode system, which consists of Kerr-like medium and down conversion process, called the Kerr-down conversion system. Under a certain condition we can obtain an exact solutio...

Quantum properties of the codirectional three-mode Kerr nonlinear coupler
In the present communication, we consider the quantum properties for the codirectional three-mode Kerr nonlinear coupler. We investigate single-, two- and three-mode quadrature squeezing, Wigner function and ...

Evolution of cat states in a dissipative parametric amplifier: decoherence and entanglement
The evolution of the Schrödinger-cat states in a dissipative parametric amplifier is examined. The main tool in the analysis is the normally ordered characteristic function. Squeezing, photon-number distributi...

Statistical properties of a solvable three-boson squeeze operator model
In the present paper we introduce a new squeeze operator, which is related to the time-dependent evolution operator for Hamiltonian representing mutual interaction between three different modes. Squeezing phen...
