Born-Infeld-Einstein theory with matter
The field equations associated with the Born-Infeld-Einstein action including matter are derived using a Palatini variational principle. Scalar, electromagnetic, and Dirac fields are considered. It is shown that an action can be chosen for the scalar field that produces field equations identical to the usual Einstein field equations minimally coupled to a scalar field. In the electromagnetic an...
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 کاملBlack 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 کاملMonopoles in non-Abelian Einstein-Born-Infeld Theory
We study static spherically symmetric monopole solutions in non-Abelian Einstein-Born-Infeld-Higgs model with normal trace structure. These monopoles are similar to the corresponding solution with symmetrised trace structure and are existing only up to some critical value of the strength of the gravitational interaction. In addition, similar to their flat space counterpart, they also admit a cr...
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...
