Abstract

Understanding the dynamic evolution of quantum systems have a key role in understanding and applicability of phenomena involved in computing and quantum information. In this presentation, we discuss the quantum dynamics of a system comprising two atoms of two levels microtoroidal coupled to a resonator in different ways. In a first arrangement atoms are neighbors enough so that the dipolar interaction between them cannot be neglected. In a second situation is the generation of entanglement in the bad ring resonator regime”, where one of the atoms is not resonant with the modes of the resonator nor interacts with another atom, it only works as a deformation of the ring resonator. We show that the entanglement between the two atoms is strongly dependent on the dipolar interaction between the atoms and we have found an enhancement of the entanglement correlated to the average number of thermal photons when the modes of resonator are prepared in a thermal states. We have observed that depending on the preparation of initial state may occur phenomenon of death rise tangling between atoms. Depending upon the intensity of the mean number of photons in the thermal field and the coupling between the atoms with the resonator is possible to generate maximum entanglement between atoms even in the regime of high temperature.
