Talk Title: "Topology and holographic entanglement entropy"


The Ryu-Takayanagi prescription gives a striking relationship between quantum mechanics and geometry, equating entropy of entanglement in holographic field theories with the area of a minimal surface. It has been known for some time that a restriction on the topology of the minimal surface is required for consistency. I’ll describe how this `homology constraint’ follows, under appropriate assumptions, from a Euclidean quantum gravity derivation of the holographic entanglement entropy formula, and what this teaches us about the subtleties of the replica trick in holography.
