Entanglement Dynamics for Two Atoms Inside a Cavity
An analytical treatment is provided of some different classes of two atoms having two or three energy levels whose dynamics show the presence of different entanglement. The phenomenon of sudden death of entanglement is investigated subject to different initial states settings. We find that for an initial Fock state, the presence of one or more photons in the cavity is ... إقراء المزيد

Dynamics of an atom coupled through a parametric frequency converter with quantum and classical fields
n this communication we introduce a model of a two-level system which represents the interaction between an atom and external quantum and classical electric fields through a parametric frequency converter. We show that the system can be reduced to an effective Jaynes–Cummings model by adequate adjustment of the field coupling in the frequency converter. The atom dynamics and the atom-quantum ... إقراء المزيد

Dynamics of impurity: Local and non-local information for two non-identical qubits
From the separability point of view the problem of two ions interact with a single cavity mode is investigated. The density matrix is calculated and used to discuss the entanglement and to examine the dynamics of the local and non-local information. Our examination concentrated on the variation in the mean photon number and the ratio of the coupling parameters. Furthermore, ... إقراء المزيد
