|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
