Description
In this talk, I will discuss the behaviour of the Euclidean path integral at low temperatures in the context of AdS_3 supergravity, highlighting the difference between near-extremal and near-bps limits. In our work, we analyzed quantum fluctuations in both the near-horizon and asymptotic regions and clarified various aspects of the bosonic fluctuations (namely, the rotational modes and gauge modes) that have been confusing in the literature. We highlight the role of boundary conditions in AdS_3, and show in particular that the gravitational path integral in the near-horizon region is inequivalent to that around the full BTZ solution at low temperature.
