One-Loop Correction to the AdS/BCFT Partition Function in the Three Dimensional Pure Gravity
arXiv:2106.00206 · doi:10.1103/PhysRevD.105.026023
Abstract
We calculate the tree-level partition function of Euclidean BTZ black hole with the end of the world branes (ETW branes) for arbitrary tension and the one-loop partition function of Euclidean thermal in the presence of a tensionless ETW brane with the Neumann boundary condition. At the tree level, our results match with the previous ones in non-rotating cases, but at the one-loop level, our results contain unexpected terms, which contain the fluctuations of the ghost fields. However particularly in the case where the chemical potential is zero, we get a similar form as the original result in AdS/CFT case, but the exponent is slightly changed. In this case the ghost contribution looks going away and the partition function becomes physical in a sense that the coefficients of the expansion in powers of are positive, which means that the number of states at the level is always positive.
