Local field modulated entanglment among three distant atoms

چکیده
We extend the scheme for that proposed by S. Mancini and S. Bose (Phys. Rev. A 70, 022307(2004)) to the case of triple-atom. Under mean field approximation, we obtain an effective Hamiltonian of triplebody 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. PACS number: 03.67.-a, 03.67.-Hz, 42.81.Qb

Field tuned atom-atom entanglement via diople-dipole interaction
We propose a simple scheme, in which only one atom couples to a cavity field, to entangle two two-level atoms. We connect two atoms with dipole-dipole interaction since one of them can move around the cavity. The results show that the peak entanglment does not depend on dipoledipole interaction strength but on field density at a certain controlling time. So the field density can act as a switch...
