BTZ Black Hole Entropy in Higher Curvature Gravity
For the BTZ black hole in the Einstein gravity, a statistical entropy has been calculated to be equal to the Bekenstein-Hawking entropy. In this paper, its statistical entropy in the higher curvature gravity is calculated and shown to be equal to the one derived by using the Noether charge method. This suggests that the equivalence of the geometrical and statistical entropies of the black hole ...
متن کاملCanonical entropy of three-dimensional BTZ black hole
Recently, Hawking radiation of the black hole has been studied using the tunnel effect method. It is found that the radiation spectrum of the black hole is not a strictly pure thermal spectrum. How does the departure from pure thermal spectrum affect the entropy? This is a very interesting problem. In this paper, we calculate the partition function by energy spectrum obtained from tunnel effect...
متن کاملWhat We Don’t Know about BTZ Black Hole Entropy
With the recent discovery that many aspects of black hole thermodynamics can be effectively reduced to problems in three spacetime dimensions, it has become increasingly important to understand the “statistical mechanics” of the (2+1)-dimensional black hole of Bañados, Teitelboim, and Zanelli (BTZ). Several conformal field theoretic derivations of the BTZ entropy exist, but none is completely s...
متن کاملQuantum Liouville theory and BTZ black hole entropy
In this paper I give an explicit conformal field theory description of (2+1)dimensional BTZ black hole entropy. In the boundary Liouville field theory I investigate the reducible Verma modules in the elliptic sector, which correspond to certain irreducible representations of the quantum algebra Uq(sl2)⊙Uq̂(sl2). I show that there are states that decouple from these reducible Verma modules in a s...
متن کاملBlack hole entropy in two dimensions.
Black hole entropy is studied for an exactly solvable model of two-dimensional gravity[1], using recently developed Noether charge techniques[2]. This latter approach is extended to accomodate the non-local form of the semiclassical effective action. In the two-dimensional model, the final black hole entropy can be expressed as a local quantity evaluated on the horizon. This entropy is shown to...
