Dynamics of two atoms coupled to a cavity field
The problem of the interaction of two-level atoms with a cavity field has been already addressed in the literature [1, 2]. This constitutes an interesting quantum optical system, given that it involves three fully quantized subsystems, and also admits an exact solution. The investigation of tripartite systems is particularly attractive specially due to the interest in three-system entanglement with implications on quantum information, for instance . Nevertheless, it seems that such a physical situation has been not fully explored, and deserves further investigation. In most. treatments, the atoms are supposed to be either both resonant. with the field  or both nonresonant . We have two subsystems in principle able to store quantum information and one subsystem (field) able to transmit quantum information, and one may ask about what kind of correlations could arise between the atomic subsystems in virtue of their interaction with the field. Here we consider a different (asymmetric) situation; one atom resonant with the cavity field and the other very far from resonance.
