Monopole Black Hole Skyrmions

Charged black hole solutions with pion hair are discussed. These can be used to study monopole black hole catalysis of proton decay. There also exist multi-black hole skyrmion solutions with BPS monopole behaviour.

Possible Effects of a Cosmological Constant on Black Hole Evolution

We explore possible effects of vacuum energy on the evolution of black holes. If the universe contains a cosmological constant, and if black holes can absorb energy from the vacuum, then black hole evaporation could be greatly suppressed. For the magnitude of the cosmological constant suggested by current observations, black holes larger than ∼ 4× 10 g would accrete energy rather than evaporate...

New Hairy Black Holes with Negative Cosmological Constant

Black hole solutions with nonspherical event horizon topology are shown to exist in an EinsteinYang-Mills theory with negative cosmological constant. The main characteristics of the solutions are presented and differences with respect to the spherically symmetric case are studied. The stability of these configurations is also addressed. PACS: 04.40; 04.70.-s; 98.80.E Although anti-de Sitter (Ad...

Casimir Effect, Achucarro-Ortiz Black Hole and the Cosmological Constant

We treat the two-dimensional projection of the (2 + 1) BTZ black hole (known as Achucarro-Ortiz black hole or as (1+1) dilatonic black hole) as a Casimir-type system. The stress tensor of a massless scalar field satisfying Dirichlet boundary conditions on two one-dimensional “walls” (“Dirichlet walls”) is explicitly calculated in three different vacua. Without employing known regularization tec...

Tunnelling with a Negative Cosmological Constant

The point of this paper is see what light new results in hyperbolic geometry may throw on gravitational entropy and whether gravitational entropy is relevant for the quantum origin of the univeres. We introduce some new gravitational instantons which mediate the birth from nothing of closed universes containing wormholes and suggest that they may contribute to the density matrix of the universe...
