Black Hole Entropy from Horizon Conformal Field Theory
String theory and “quantum geometry” have recently offered independent statistical mechanical explanations of black hole thermodynamics. But these successes raise a new problem: why should models with such different microscopic degrees of freedom yield identical results? I propose that the asymptotic behavior of the density of states at a black hole horizon may be determined by an underlying sy...
متن کاملBlack Hole Entropy from Conformal Field Theory in Any Dimension
Restricted to a black hole horizon, the “gauge” algebra of surface deformations in general relativity contains a Virasoro subalgebra with a calculable central charge. The fields in any quantum theory of gravity must transform accordingly, i.e., they must admit a conformal field theory description. Applying Cardy’s formula for the asymptotic density of states, I use this result to derive the Bek...
متن کاملBlack Hole Entropy from Conformal Field Theory in Any Dimension
When restricted to the horizon of a black hole, the " gauge " algebra of surface deformations in general relativity contains a physically important Virasoro subalgebra with a calculable central charge. The fields in any quantum theory of gravity must transform under this algebra; that is, they must admit a conformal field theory description. With the aid of Cardy's formula for the asymptotic de...
متن کاملExact Black Hole Entropy Bound in Conformal Field Theory
We show that a Rademacher expansion can be used to establish an exact bound for the entropy of black holes within a conformal field theory framework. This convergent expansion includes all subleading corrections to the Bekenstein-Hawking term.
متن کاملNear-horizon conformal symmetry and black hole entropy.
Near an event horizon, the action of general relativity acquires a new asymptotic conformal symmetry. For two-dimensional dilaton gravity, this symmetry results in a chiral Virasoro algebra, and Cardy's formula for the density of states reproduces the Bekenstein-Hawking entropy. This lends support to the notion that black hole entropy is controlled universally by conformal symmetry near the hor...
