New aspects of the interaction between two atoms and nonlinear optical fields

We present a new kind of interaction between two two-level atoms and optical field initially in deformed bosonic coherent states. Using the concurrence and negativity as measures of entanglement, we investigate the nonlocal correlation between atom–atom and atom–field in terms of the parameters involved in the whole system. We report some important results related to this new kind of interaction such as sudden death, sudden birth, and entanglement stabilization.
