Holographic mutual information for singular surfaces
Journal of High Energy Physics
We study corner contributions to holographic mutual information for entangling regions composed of a set of disjoint sectors of a single infinite circle in three-dimensional conformal field theories. In spite of the UV divergence of holographic mutual information, it exhibits a first order phase transition. We show that tripartite information is also divergent for disjoint sectors, which is in contrast with the well-known feature of tripartite information being finite even when entanglingdoi:10.1007/jhep12(2015)082 fatcat:6o6t7lit5nhn7d7mtjintgvgia
