5D Rotating Black Holes and the nAdS$_2$/nCFT$_1$ Correspondence
Abstract
We study rotating black holes in five dimensions using the nAdS/nCFT correspondence. A consistent truncation of pure Einstein gravity (with a cosmological constant) in five dimensions to two dimensions gives a generalization of the Jackiw-Teitelboim theory that has two scalar fields: a dilaton and a squashing parameter that breaks spherical symmetry. The interplay between these two scalar fields is non trivial and leads to interesting new features. We study the holographic description of this theory and apply the results to the thermodynamics of the rotating black hole from a two dimensional point of view. This setup challenges notions of universality that have been advanced based on simpler models: we find that the mass gap of Kerr-AdS corresponds to an undetermined effective coupling in the nAdS/nCFT theory which depends on ultraviolet data.
