Entropy of Scalar Field in 3+1 Dimensional Reissner-Nordstrom de Sitter Black Hole Background
We consider the thermodynamics of minimally coupled massive scalar field in 3+1 dimensional Reissner-Nordstrom de Sitter black hole background. The brick wall model of ’t Hooft is used. When Schwarzschild like coordinates are used it is found that two radial brick wall cut-off parameters are required to regularize the solution. Free energy of the scalar field is obtained through counting of sta...
متن کاملReissner-Nordstrom Black Hole in Gravity Localized Models
We investigate the possibility of having the electrically charged Reissner-Nordstrom black hole in the gravity localized models in a brane world. It is shown that the ReissnerNordstrom black hole exists as a solution in the 5D Randall-Sundrum domain wall model if there is the U(1) bulk gauge field. We find that the charged black hole is localized on a 3-brane even if zero mode of the bulk gauge...
متن کاملInformation consumption by Reissner-Nordström black holes.
The low-energy scattering of charged fermions by extremal magnetic Reissner-Nordstrom black holes is analyzed in the large-1V and S-wave approximations. It is shown that (in these approximations) information is carried into a causally inaccessible region of spacetime, and thereby effectively lost. It is also shown that there is an infinite degeneracy of quantum black hole ground states, or "rem...
متن کاملDeformed Reissner–Nordstrom solutions in noncommutative gravity
The leading order corrections to Reissner–Nordstrom solutions of the Einstein’s equations on noncommutative space time have been worked out basing on a noncommutative gauge theory of gravity. From the corrcted metric the horizons have been derived and the curvature scalar is also computed. The introduction of noncommutativity leads to the removal of the coordinate singularities.
متن کاملThe Caedy-Verlinde formula and entropy of Topological Reissner-Nordström black holes in de Sitter spaces
In this paper we discuss the question of whether the entropy of cosmological horizon in Topological Reissner-Nordströmde Sitter spaces can be described by the Cardy-Verlinde formula, which is supposed to be an entropy formula of conformal field theory in any dimension. Furthermore, we find that the entropy of black hole horizon can also be rewritten in terms of the Cardy-Verlinde formula for th...
