Entanglement entropy of two dimensional systems and holography
arXiv:0806.2661 · doi:10.1088/1126-6708/2008/12/068
Abstract
In this note a new method for computing the entanglement entropy of a CFT holographically is explored. It consists of finding a bulk background with a boundary metric that has the conical singularities needed to compute the entanglement entropy in the usual QFT definition. An explicit calculation is presented for d=2.
