Superradiance and the Statistical-Mechanical Entropy of Rotating BTZ Black Holes
We have considered the divergence structure in the brick-wall model for the statistical mechanical entropy of a quantum field in thermal equilibrium with a rotating BTZ black hole. Especially, the contribution to entropy from superradiant modes is carefully incorporated, leading to a very different result from known ones in the literature. That is, it is positive and also has a leading order di...
متن کاملRotating BTZ Black Holes
We have considered the divergence structure in the brick-wall model for the statistical mechanical entropy of a quantum field in thermal equilibrium with a black hole which rotates. Especially, the contribution to entropy from superradiant modes is carefully incorporated, leading to a result for this contribution which corrects some previous errors in the literature. It turns out that the previ...
متن کاملStatistical entropy and AdS/CFT correspondence in BTZ black holes
We study AdS/CFT correspondence in the case of AdS3. We obtain the statistical entropy of the BTZ black hole in terms of the correct central charge and the conformal dimensions for the states corresponding to the BTZ black hole. We point out the difference between our method and the old fashioned approaches based on SL(2, R) Wess-Zumino-Witten model or Liouville theory. email: [email protected] e...
متن کاملQuasi-Poisson actions and massive non-rotating BTZ black holes
Using ideas from an article of P. Bieliavsky, M. Rooman and Ph. Spindel on BTZ black holes, I construct a family of interesting examples of quasi-Poisson actions as defined by A. Alekseev and Y. Kosmann-Schwarzbach. As an application, I obtain a genuine Poisson structure on SL(2, R) which induces a Poisson structure on a BTZ black hole.
متن کاملCondition for Superradiance in Higher-dimensional Rotating Black Holes
It is shown that the superradiance modes always exist in the radiation by the (4 + n)-dimensional rotating black holes. Using a Bekenstein argument the condition for the superradiance modes is shown to be 0 < ω < mΩ for the scalar, electromagnetic and gravitational waves when the spacetime background has a single angular momentum parameter about an axis on the brane, where Ω is a rotational fre...
