No Scalar Hair Theorem for a Charged Spherical Black Hole
This paper consolidates the no scalar hair theorem for a charged spherically symmetric black hole in four dimensions in general relativity as well as in all scalar tensor theories, both minimally and nonminimally coupled, when the effective Newtonian constant of gravity is positive. However, there is an exception when the matter field itself is coupled to the scalar field, such as in dilaton gr...
متن کاملScalar Hair Theorem for a Charged Spherical Black Hole
This paper shows that no scalar hair can exist for a spherically symmetric charged black hole. This is true for minimally as well as non-minimally coupled scalar fields. If, however, the scalar field is coupled nonminimally to the matter lagrangian also, nontrivial scalar hair may exist. One example of the latter may be found in dilaton gravity.
متن کاملElectrically charged black hole with scalar hair
An electrically charged black hole solution with scalar hair in four dimensions is presented. The self-interacting scalar field is real and it is minimally coupled to gravity and electromagnetism. The event horizon is a surface of negative constant curvature and the asymptotic region is locally an AdS spacetime. The asymptotic fall-off of the fields is slower than the standard one. The scalar f...
متن کاملEnergy Distribution of a Charged Black Hole with a Minimally Coupled Scalar Field
Using three different energy-momentum complexes, the Einstein, Landau-Lifshitz, and Papapetrou prescriptions, we calculate the energy of an electrically charged black hole exact solution with a self-interacting, minimally-coupled scalar field and the asymptotic region locally an Anti-deSitter spacetime. Writing the metric in Kerr-Schild Cartesian coordinates, we demonstrate that this metric bel...
متن کاملMassive charged scalar field in a Reissner - Nordstrom black hole background : quasinormal ringing
We compute characteristic (quasinormal) frequencies corresponding to decay of a massive charged scalar field in a Reissner-Nordstrom black hole background. It proves that, contrary to the behavior at very late times, at the stage of quasinormal ringing the neutral perturbations will damp slower than the charged ones. In the limit of the extremal black hole the damping rate of charged and neutra...
