Abstract: We present the results of the interaction of identical two-level atoms with a system formed by two identical coupled cavities via evanescent field. With new bosonic operators (normal nodes), the interaction Hamiltonian between the cavities can be diagonalized. In a particular case, we can eliminate the interaction of the atoms with the nonresonant normal modes reducing the system to the interaction of the atom with a single-mode (like JCM). As an application of this interaction, we analyze the entanglement between distant atoms. We present two related simple procedures to generate two atoms maximally entangled state (EPR pair) interacting (i)successively (atoms passing through the cavities at different moments) and (ii) simultaneously (at the same time) with the coupled cavities system. Moreover, in contrast with other schemes, we can use identical atoms which simplifies in a experiment point of view. © 2008 American Institute of Physics.
