Abstract
摘要 |
Supersymmetric localization is a powerful tool that can provide us with some exact results of quantum field theories. By applying it to gravity, one can test the AdS/CFT correspondence more precisely and in some cases compute the black hole entropy with subleading corrections. In this talk, I will discuss some concrete examples. For the 4d case, we consider the 4d N=2 off-shell supergravity on topological black hole, which provides the gravity dual of the ABJM theory on the boundary S1*H2. We can compute the black hole entropy with the logarithmic correction beyond the classical Bekenstein-Hawking result, and test the identification of the bulk black hole entropy with the entanglement entropy of the boundary CFT. For the 3d gravity, the strategy is similar but slightly different. We can map the 3d pure gravity to the supersymmetric Chern-Simons theory and then perform the localization. In this way, we discuss the entropy of BTZ black holes. Some possible applications to the Sachdev-Ye-Kitaev model and the corresponding gravity dual will also be discussed. The talk is based on my recent joint work arXiv:1705.01896 and some work in progress. |
