The case of two disjoint regions allows to explore many interesting aspects of the entanglement in Quantum Field Theory. In two dimensional Conformal Field Theories, the Renyi entropies for two disjoint intervals do not depend only on the central charge, like the single interval case, but on all the operator content of the theory. The method also allows to find new QFT results about negativity, which is a measure of entanglement for mixed states. In the context of the holographic correspondence, the holographic entanglement entropy for disjoint regions makes manifest the need of understanding unexplored regimes of parameters.
