Black hole entropy from nearhorizon microstates
Abstract
Black holes whose nearhorizon geometries are locally, but not necessarily globally, AdS_{3} (threedimensional antide Sitter space) are considered. Using the fact that quantum gravity on AdS_{3} is a conformal field theory, we microscopically compute the black hole entropy from the asymptotic growth of states. Precise numerical agreement with the BekensteinHawking area formula for the entropy is found. The result pertains to any consistent quantum theory of gravity, and does not use string theory or supersymmetry.
