Black holes in three-dimensional Einstein-Born-Infeld-dilaton theory
The three-dimensional static and circularly symmetric solution of the Einstein-BornInfeld-dilaton system is derived. The solutions corresponding to low energy string theory are investigated in detail, which include black hole solutions if the cosmological constant is negative and the mass parameter exceeds a certain critical value. Some differences between the Born-Infeld nonlinear electrodynam...
متن کاملSolitons and black holes in Einstein-Born-Infeld-dilaton theory
Static spherically symmetric asymptotically flat solutions to the U(1) BornInfeld theory coupled to gravity and to a dilaton are investigated. The dilaton enters in such a way that the theory is SL(2, R)symmetric for a unit value of the dilaton coupling constant. We find globally regular solutions for any value of the effective coupling which is the ratio of the gravitational and dilaton coupli...
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 کاملNon-Abelian Einstein-Born-Infeld Black Holes
We construct regular and black hole solutions in SU(2) Einstein-Born-Infeld theory. These solutions have many features in common with the corresponding SU(2) Einstein-Yang-Mills solutions. In particular, sequences of neutral nonabelian solutions tend to magnetically charged limiting solutions, related to embedded abelian solutions. Thermodynamic properties of the black hole solutions are addres...
متن کاملEinstein-Born-Infeld-dilaton black holes in non-asymptotically flat spacetimes
We derive exact magnetically charged, static and spherically symmetric black hole solutions of the four-dimensional Einstein-Born-Infeld-dilaton gravity. These solutions are neither asymptotically flat nor (anti)-de Sitter. The properties of the solutions are discussed. It is shown that the black holes are stable against linear radial perturbations.
