Where are the BTZ Black Hole Degrees of Freedom? The Rotating Case

Abstract

Recent work has shown that the entropy of the non-rotating BTZ black hole can be derived from a dual conformal description at any spatial location. In this followup it is shown that a dual conformal description exists at any spatial location for the rotating BTZ black hole as well. As in the non-rotating case, two copies of the central charge $c^{\pm} = 3\ell/2G$ are recovered and the microcanonical Cardy formula yields the correct Bekenstein-Hawking entropy.
