ENTANGLEMENT IN NONDEGENERATE TWO-PHOTON TAVIS - CUMMINGS MODEL

Abstract

The influence of dipole-dipole interaction on the entanglement between twoatoms with different initial W-like states in Tavis Cummings model withdegenerate two-photon transitions has been investigated. The results show thatthe dipole-dipole interaction leads to the stabilization of atomic entanglement.

The dynamics of entanglement in two-atom Tavis-Cummings model with non-degenerate two-photon transitions for tripartite entangled W-like states

Eugene K. Bashkirov, Michail S. Mastyugin

The influence of dipole-dipole interaction on the entanglement between two atoms with different initial entangled W-like states in Tavis-Cummings model with degenerate two-photon transitions has been investigated. The results show that the entanglement between two atoms can be increased by means of dipole-dipole interaction and for some initial states the entanglement sudden death effect can be weakened.

Eugene K. Bashkirov, M.S. Mastygin

The influence of dipole-dipole interaction on the entanglement between two atoms and field in many-photon Tavis — Cummings with coherent cavity mode has been investigated. The results show that in the case of one-photon model the dipole-dipole interaction leads to the stabilization of atom-field entanglement.

The influence of dipole-dipole interaction on entanglement in nondegenerate two-photon Tavis-Cummings model with atomic coherence

Eugene K. Bashkirov, Michail S. Mastuygin

The entanglement of two dipole-coupled atoms with nondegenerate two-photon transitions interacting with two-mode field in lossless cavity has been investigated. It shows that the entanglement is dependent on the initial atomic states. The possibility of considerable growth of atomic entanglement due atomic coherence and dipole-dipole interaction is shown in the case of great mean values of thermal photons.

Influence of the Dipole-Dipole Interaction between Atoms on the Entanglement of Tavis-Cummings Model with Two Photon Process

Xie Fang-sen

The evolution of the entanglement in the T-C model was studied in condition of the dipole-dipole interaction between two atoms.The system will evolve into three-body w-entangled state,when the initial state of system is|2,g1,g2〉 or γ|0,g1,e2〉+1-γ2|0,e1,g2〉.The evolution of entanglement changes when the initial state ofthe system are different.

The influences of dipole–dipole interaction and detuning on the sudden death of entanglement between two atoms in the Tavis–Cummings model

Chen Li, Shao Xiao-Qiang, Zhang Shou

The influences of dipole-dipole interaction and detuning on the entanglement between two atoms with different initial tripartite entangled W -like states in the Tavis–Cummings model have been investigated by means of Wootters' concurrence, respectively. The results show that the entanglement between the two atoms can be enhanced via appropriately tuning the strength of dipole-dipole interaction of two atoms or the detunings between atom and cavity, and the so-called sudden death effect can be weakened simultaneously.
