Entanglement Entropy of AdS Black Holes

We review recent progress in understanding the entanglement entropy of gravitational configurations for anti-de Sitter gravity in two and three spacetime dimensions using the AdS/CFT correspondence.We derive simple expressions for the entanglement entropy Home Media Players of two- and three-dimensional black holes.In both cases, the leading term of the entanglement entropy in the large black hole mass expansion reproduces exactly the Bekenstein-Hawking entropy, whereas the subleading term behaves logarithmically.In particular, for TOUGH1 CACTUS SADDLE BAG the BTZ black hole the leading term of the entanglement entropy can be obtained from the large temperature expansion of the partition function of a broad class of 2D CFTs on the torus.
