Evaluation of pairwise entanglement in translationally invariant systems with the random phase approximation
We discuss a general mean field plus random phase approximation (RPA) for describing composite systems at zero and finite temperature. We analyze in particular its implementation in finite systems invariant under translations, where for uniform mean fields it requires just the solution of simple loc...
