Three-dimensional black hole entropy
نویسندگان
چکیده
We discuss in detail the properties of gravity with a negative cosmological constant as viewed in Cherns-Simons theory on a line times a disc. We reanalyze the problem of computing the BTZ entropy, and show how the demand of unitarity and modular invariance of the boundary conformal field theory severely constrain proposals in this framework. On leave from Department of Physics, Graduate School of Science, Osaka University, Osaka, Japan.

Entropy of extreme three-dimensional charged black holes
It is shown that three-dimensional charged black holes can approach the extreme state at nonzero temperature. Unlike even dimensional cases, the entropy for the extreme three-dimensional charged black hole is uniquely described by the BekensteinHawking formula, regardless of different treatments of preparing the extreme black hole, namely, Hawking’s treatment and Zaslavskii’s treatment. PACS nu...
متن کاملEntropy of the three dimensional Schwarzschild - de Sitter black hole
We study the three dimensional Schwarzschild-de Sitter (SdS3) black hole which corresponds essentially to a conical defect. We compute the mass of the SdS3 black hole from the correct definition of the mass in asymptotically de Sitter space. Then we clarify the relation between the mass, entropy and temperature for this black hole without any ambiguity. Also we establish the SdS3/CFT2-correspon...
متن کاملThe phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
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 کاملBlack Hole Entropy in the presence of Chern-Simons Terms
We derive a formula for the black hole entropy in theories with gravitational Chern-Simons terms, by generalizing Wald’s argument which uses the Noether charge. It correctly reproduces the entropy of three-dimensional black holes in the presence of Chern-Simons term, which was previously obtained via indirect methods.
متن کاملEmbeddings of the Virasoro algebra and black hole entropy
Three-dimensional gravity was put forward by Deser, Jackiw and ’t Hooft [1] as an interesting toy model for gravitational physics. It was then argued in [2] (see also [3]) that it defines a soluble and finite quantum field theory. Questions such as what are the microscopical degrees of freedom giving rise to the Bekenstein-Hawking entropy in three dimensions should then have an answer. However,...
