Gravitating Sphalerons and Sphaleron Black Holes in Asymptotically Anti-de Sitter Spacetime
نویسندگان
چکیده
Numerical arguments are presented for the existence of spherically symmetric regular and black hole solutions of the EYMH equations with a negative cosmological constant. These solutions approach asymptotically the anti-de Sitter spacetime. The main properties of the solutions and the differences with respect to the asymptotically flat case are discussed. The instability of the gravitating sphaleron solutions is also proven.

The C-metric is one of few known exact solutions of Einstein's field equations which describes the gravitational field of moving sources. For a vanishing or positive cosmological constant, the C-metric represents two accelerated black holes in asymptotically flat or de Sitter spacetime. For a negative cosmological constant the structure of the spacetime is more complicated. Depending on the val...
متن کاملFormation of Topological Black Holes from Gravitational Collapse
We consider the gravitational collapse of a dust cloud in an asymptotically anti de Sitter spacetime in which points connected by a discrete subgroup of an isometry subgroup of anti de Sitter spacetime are identified. We find that black holes with event horizons of any topology can form from the collapse of such a cloud. The quasilocal mass parameter of such black holes is proportional to the i...
متن کاملBlack Holes in Anti-de Sitter Spacetime
Black holes in anti-de Sitter (AdS) spacetime are known to be thermodynamically stable against radiation, unlike their asymptotically flat counterparts. Moreover, Hawking and Page discovered that they exhibit a first-order phase transition. This was reinterpreted by Witten using the AdS/CFT correspondence as a confinement/deconfinement transition in the quark-gluon plasma. Extending the gauge/g...
متن کاملSkyrmion and Skyrme-Black holes in de Sitter spacetime
Numerical arguments are presented for the existence of regular and black hole solutions of the EinsteinSkyrme equations with a positive cosmological constant. These classical configurations approach asymptotically the de Sitter spacetime. The main properties of the solutions and the differences with respect to the asymptotically flat ones are discussed. It particular our results suggest that, f...
متن کاملEntropy of Extremal Black Holes in Asymptotically Anti-de Sitter Spacetime
Unlike the extremal Reissner-Nordström black hole in ordinary spacetime, the one in anti-de Sitter spacetime is a minimum of action and has zero entropy if quantization is carried out after extremaliza-tion. However, if extremalization is carried out after quantization, then the entropy is a quarter of the area as in the usual case. While the entropy of ordinary (non-extremal) black holes has b...
