Local field modulated entanglment among three distant atoms
Abstract
We extend the scheme for that proposed by S. Mancini and S. Bose (Phys. Rev. A bf70, 022307(2004)) to the case of triple-atom. Under mean field approximation, we obtain an effective Hamiltonian of triple-body Ising-model interaction. Furthermore, we stress on discussing the influence of the existence of a third-atom on the two-atom entanglement and testing the modulation effects of locally applied optical fields and fiber on the entanglement properties of our system.
