We explore various aspects of the entropy of the donor–acceptor QD system (GaAs – (Ga, Al)As) under the effect of terahertz excitation and magnetic field. We solve the optical Bloch equations of the system in presence of the total dephasing rate.

In this paper, we present the analytical solution for the model that describes the interaction between a three level atom and two systems of N-two level atoms. The effect of the quantum numbers on the atomic inversion and the purity, for some special

In this paper, we derive the time dependent solution of the effective master equation for the reduced density matrix operator of a two level atom driven by a coherent laser field and damped by a finite bandwidth squeezed vacuum. The results show that

We find a class of spin environment at finite temperature in the thermodyna mics limit models where individual quantum trajectories may depend on parameters that are undetermined by the full open system evolution. Our criteria are functions of the gi

In this paper, we examine a class of special cases of a two-qubit system under time evolution, in the presence of local squeezed reservoirs, we report some results related to the occurrence of so-called entanglement sudden death (ESD) of two cases of

In this paper, we derive the time-dependent solution of the effective master equation for the reduced density matrix operator of a two-level atom driven by a coherent laser field and damped by a finite-bandwidth squeezed vacuum. The master equation h

In this paper, we derive the time dependent solution of the effective master equation for the reduced density matrix operator of a two-level atom driven by a strong classical field and damped into a “modelled” reservoir with non-flat density of m
