Two interacting atoms in a cavity: Entanglement vs decoherence — •Emerson Sadurní1, 2, Thomas Seligman2, 3, and Mauricio Torres2 — 1Institut fuer Quantenphysik, Ulm Universitaet — 2Instituto de Ciencias Físicas, UNAM. México — 3Centro Internacional de Ciencias, UNAM, México
We address the problem of two interacting atoms of different species inside a cavity and find the explicit solutions of the corresponding eigenvalue problem. Closed expressions for concurrence and purity as a function of time when the cavity is prepared in a number state are found. The behavior in the concurrence-purity plane is discussed.
