Abstract: I will talk about a new calculation of the Renyi entropy of a general CFT in D-dimensions with a spherical entangling surface in terms of certain thermal partition functions and it's application to compute the entanglement entropy in various holographic models. This approach is presented in arXiv:1110.1084v1[hep-th] and arXiv:1102.0440[hep-th]. This method is so useful to realize a holographic descripsion for some CFT calculations found in arXiv:0006196v3[hep-th], which considered correlation functions of twist operators in a symmetric orbifold CFT.
