Black Hole Entropy from Conformal Field Theory in Any Dimension
نویسنده
چکیده
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 density of states in a conformal field theory, I use this description to derive the Bekenstein-Hawking entropy. This method is universal—it holds for any black hole, in any dimension, and requires no details of quantum gravity—but it is also explicitly statistical mechanical, based on the counting of microscopic states.

Comments on “ Black Hole Entropy from Conformal Field Theory in Any Dimension ”
In a recent letter, Carlip proposed a generalization of the Brown-Henneaux-Strominger construction to any dimension. We present two criticisms about his formulation.
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 کاملLogarithmic correction to the Cardy-Verlinde formula in Achucarro-Oritz Black Hole
In this paper we calculate leading order correction due to small statistical fluctuations around equilibrium, to the Bekenstein-Hawking entropy formula for the Achucarro-Oritz black hole, which is the most general two-dimensional black hole derived from the three-dimensional rotating Banados-Teitelboim-Zanelli black hole. Then we obtain the same correction to the Cardy-Verlinde entropy formula ...
متن کاملNear-Horizon Virasoro Symmetry and the Entropy of de Sitter Space in Any Dimension
De Sitter spacetime is known to have a cosmological horizon that enjoys thermodynamic-like properties similar to those of a black hole horizon. In this note we show that a universal argument can be given for the entropy of de Sitter spacetime in arbitrary dimensions, by generalizing a recent near horizon symmetry plus conformal field theory argument of Carlip for black hole entropy. The implica...
متن کاملLogarithmic correction to the Cardy-Verlinde formula in Topological Reissner-Nordström de Sitter Space
In this paper we compute leading order correction due to small statistical fluctuations around equilibrium, to the Cardy-Verlinde entropy formula (which is supposed to be an entropy formula of conformal field theory in any dimension) of a Topological Reissner-Nordstrom black hole in de Sitter space. ∗E-mail: [email protected]
