Charged Nariai Black Holes With a Dilaton
The Reissner-Nordström-de Sitter black holes of standard Einstein-Maxwell theory with a cosmological constant have no analogue in dilatonic theories with a Liouville potential. The only exception are the solutions of maximal mass, the Charged Nariai solutions. We show that the structure of the solution space of the Dilatonic Charged Nariai black holes is quite different from the non-dilatonic c...
متن کاملWhat is the True Description of Charged Black Holes?
If string theory describes nature, then charged black holes are not described by the Reissner-Nordstrøm solution. This solution must be modified to include a massive dilaton. In the limit of vanishing dilaton mass, the new solution can be found by a generalization of the Harrison transformation for the Einstein-Maxwell equations. These two solution generating transformations and the resulting b...
متن کاملElectrically Charged Einstein-Born-Infeld Black Holes with Massive Dilaton
We numerically construct static and spherically symmetric electrically charged black hole solutions in Einstein-Born-Infeld gravity with massive dilaton. The numerical solutions show that the dilaton potential allows many more black hole causal structures than the massless dilaton. We find that depending on the black hole mass and charge and the dilaton mass the black holes can have either one,...
متن کاملBlack Holes Coupled to a Massive Dilaton
We investigate charged black holes coupled to a massive dilaton. It is shown that black holes which are large compared to the Compton wavelength of the dilaton resemble the Reissner-Nordström solution, while those which are smaller than this scale resemble the massless dilaton solutions. Black holes of order the Compton wavelength of the dilaton can have wormholes outside the event horizon in t...
متن کاملPair Creation of Dilaton Black Holes in Extended In ation
Dilatonic Charged Nariai instantons mediate the nucleation of black hole pairs during extended chaotic in ation. Depending on the dilaton and in aton elds, the black holes are described by one of two approximations in the Lorentzian regime. For each case we nd Euclidean solutions that satisfy the no boundary proposal. The complex initial values of the dilaton and in aton are determined, and the...
