The temporal behavior of squeezing parameters and second order correlation function is investigated for a
two atom dissipative model. The analytic expressions for considering parameters are obtained on the basis of
master equation solution for coherent input. An influence of different dissipation mechanisms onto statistics and
squeezing are considered.
The exact wave function is found in the work for the two-atom models with nondegenerate two-photon interaction
and nondegenerate raman interaction. The asymptotic solutions for system state vectors are obtained in the
approximation of strong field for considered models for different initial atom states and coherent field input.
The reduced entropy dynamics is described for various initial atomic states and coherent field input, some
conclusions about atom-field entanglement are made. We also show the possibility for the system being initially
in the pure nonentangled state to revive into this state during the evolution process for the two-atom model with
nondegenerate two-photon interaction and we obtain the times of such revivals.
The exact wave function and asymptotic expressions for the system state vectors under strong initial coherent
fields are found in the work for the two-atom models with nondegenerate two-photon interaction and nondegen-
erate Raman interaction. The atom-field entanglement is considered via linear entropy criterion. The system
revivals to unentangled states are shown to appear for both models. The disentanglement times are derived in
the work. The atom-atom entanglement induced by thermal noise is investigated for the both models.
The entropy dynamics for three-level Ξ-type atom is investigated in the article. The analytic expressions for atomic
entropy are obtained in the work, as well as exact solutions for Schr&diaero;dinger equation for wave function. The
entanglement dynamics in the system is considered on the base of reduced entropy analysis.
In this work we considered temporal behaviour of a two two-level atoms in a infinite-Q cavity with atom dissipation
for coherent and squeezed inputs. The analytic expressions for second-order correlation function and squeezing
parameters and amplitude-squeezing parameters are obtained on the basis of master equation solution. System
observables dynamics is investigated for coherent and squeezed initial field state for various system parameters values.
In this work we considered temporal behavior of squeezing and amplitude-squared squeezing for a two two-level
atoms in a finite-Q cavity with atom dissipation. The analytic expressions for squeezing parameters are obtained
on the basis of master equation solution for coherent and squeezed input. Squeezing generation conditions are
considered for various dissipation parameters values and coherent and squeezed initial input.
A nondegenerate two-photon Jaynes-Cummings model is investigated where the leakage of photon through the
cavity is taken into account. The effect of cavity damping on the mean photon number, atomic populations,
field statistics and both field and atomic squeezing is considered on the basis of master equation in dressed-state
approximation for initial coherent fields and excited atom.
The dynamics of detuned two-level Jaynes-Cummings model with multiphoton transitions in the finite Q-cavity has been considered. The time evolution of the mean photon number and atomic populations has been investigated for various values of the model parameters. The type of field statistics and photon bunching/antibunching effects has been examined.
