Entropy bound for a rotating system from Anti de Sitter black holes

چکیده
General geodesic equations of the motion of spinning systems around the (3+1)-dimensional and (2+1)-dimensional rotating anti-de Sitter black holes have been obtained. Based upon these equations, we derived the entropy bound for a rotating system from Kerr-Anti de Sitter black holes and BTZ black holes, respectively. Our result coincides with that of Hod’s derived from Kerr black hole, which shows that the entropy bound of the rotating system is neither dependent on the black hole parameters, nor on spacetime dimensions. It is a universal entropy bound. PACS number(s): 04.70.Dy, 05.70.Ce, 95.30Tg, 97.60.Lf. e-mail:[email protected] e-mail:[email protected]

ترمودینامیک سیاهچالههای چرخان و گرانش با تصحیحات مرتبه اول نظریه ریسمان
In this paper, the rotating black brane solutions with zero curvature horizon of classical gravity with first order string corrections are introduced. Although these solutions are not asymptotically anti de Sitter, one can use the counterterm method in order to compute the conserved quantities of these solutions. Here, by reviewing the counterterm method for asymptotically anti de Sitter spac...
متن کاملFive-dimensional rotating black holes in Einstein-Gauss-Bonnet theory
We present arguments for the existence of five-dimensional rotating black holes with equal magnitude angular momenta in Einstein-Gauss-Bonnet theory with negative cosmological constant. These solutions posses a regular horizon of spherical topology and approach asymptotically an Anti-de Sitter spacetime background. We discuss the general properties of these solutions and, using an adapted count...
متن کاملBubbles in Anti-de Sitter Space
We explore the bubble spacetimes which can be obtained from double analytic continuations of static and rotating black holes in anti-de Sitter space. In particular, we find that rotating black holes with elliptic horizon lead to bubble spacetimes only in dimension greater than five. For dimension greater than seven, the topology of the bubble can be non-spherical. However, a bubble spacetime is...
متن کاملRadially Excited AdS5 Black Holes in Einstein-Maxwell-Chern-Simons Theory
In the large coupling regime of the 5-dimensional Einstein–Maxwell–Chern–Simons theory, charged and rotating cohomogeneity-1 black holes form sequences of extremal and non-extremal radially excited configurations. These asymptotically global Anti-de Sitter (AdS5) black holes form a discrete set of solutions, characterised by the vanishing of the total angular momenta, or the horizon angular vel...
متن کاملHawking radiation from rotating black holes in anti-de Sitter spaces via gauge and gravitational anomalies
Robinson-Wilczek’s recent work, which treats Hawking radiation as a compensating flux to cancel gravitational anomaly at the horizon of a Schwarzschild-type black hole, is extended to study Hawking radiation of rotating black holes in anti-de Sitter spaces, especially that in dragging coordinate system, via gauge and gravitational anomalies. The results show that in order to restore gauge invar...
