Dynamics of Entanglement of Two Atoms in Two Dissipative Cavities in the Double Jaynes-Cummings Models

摘要

We consider two separated single mode disipative cavities that each containing a single two-level atom. The fields in cavities are both initially prepared in the coherent states, and the atoms are initially prepared in the singlet state |psi-& rang;=12(|eg & rang;-|ge & rang;)documentclass[12pt]. In the dispersive approximation, we show that, the entanglement between the two atoms decays to a steady value after a period of time of oscillations. We also show the impact of some parameters on the steady entanglemant between the two atoms.
