Møller Energy for the Kerr-newman Metric
The energy distribution in the Kerr-Newman space-time is computed using the Møller energy-momentum complex. This agrees with the Komar mass for this space-time obtained by Cohen and de Felice. These results support the Cooperstock hypothesis. Typeset using REVTEX ∗E-mail: [email protected]
متن کاملCardy-Verlinde Formula and Kerr-Newman-AdS4 and Kerr-Newman-dS4 black holes
The Cardy-Verlinde formula, which expresses the entropy of the conformal field theory in terms of its total energy (or the extensive energy), Casimir energy and radius of the unit sphere S, is further verified by using the KerrNewman-AdS4 and Kerr-Newman-dS4 black holes. For the Kerr-NewmanAdS4 black hole, we find that to cast the entropy of the conformal field theory into the Cardy-Verlinde fo...
متن کاملThe Application of the Newman-Janis Algorithm in Obtaining Interior Solutions of the Kerr Metric
In this paper we present a class of metrics to be considered as new possible sources for the Kerr metric. These new solutions are generated by applying the Newman-Janis algorithm (NJA) to any static spherically symmetric (SSS) “seed” metric. The continuity conditions for joining any two of these new metrics is presented. A specific analysis of the joining of interior solutions to the Kerr exter...
متن کاملThe Kerr-Newman-Gödel Black Hole
By applying a set of Hassan-Sen transformations and string dualities to the Kerr-Gödel solution of minimal D = 5 supergravity we derive a four parameter family of five dimensional solutions in type II string theory. They describe rotating, charged black holes in a rotating background. For zero background rotation, the solution is D = 5 Kerr-Newman; for zero charge it is Kerr-Gödel. In a particu...
متن کاملThermodynamic curvature and phase transitions in Kerr-Newman black holes
Singularities in the thermodynamics of Kerr-Newman black holes are commonly associated with phase transitions. However, such interpretations are complicated by a lack of stability and, more significantly, by a lack of conclusive insight from microscopic models. Here, I focus on the later problem. I use the thermodynamic Riemannian curvature scalar R as a try to get microscopic information from ...
