Black diholes

چکیده
We present and analyze exact solutions of the Einstein–Maxwell and Einstein–Maxwell– Dilaton equations that describe static pairs of oppositely charged extremal black holes, i.e., black diholes. The holes are suspended in equilibrium in an external magnetic field. We comment as well on the relation of these solutions to brane–antibrane configurations in string and M-theory.

Black diholes in five dimensions
Using a generalized Weyl formalism, we show how stationary, axisymmetric solutions of the four-dimensional vacuum Einstein equation can be turned into static, axisymmetric solutions of five-dimensional dilaton gravity coupled to a two-form gauge field. This procedure is then used to obtain new solutions of the latter theory describing pairs of extremal magnetic black holes with opposite charges...
متن کاملMacroscopic and Microscopic Description of Black Diholes
We study configurations consisting of a pair of non-extremal black holes in four dimensions, both with the same mass, and with charges of the same magnitude but opposite sign—diholes, for short. We present such exact solutions for Einstein-Maxwell theory with arbitrary dilaton coupling, and also solutions to the U(1)4 theories that arise from compactified string/M-theory. Despite the fact that ...
متن کاملConstructing more non-singular Sp-branes
In this note, we construct an array of non-singular Sp (where p = D − 4) branes in arbitrary D dimensions starting from static solutions of black p brane. These solutions carry nontrivial time dependent profiles of dilaton and associated form fields. We also study other non-singular time dependent configurations. These are obtained from proper analytic continuations of non-extremal diholes. E-m...
متن کاملAccelerating black diholes and static black di-rings
We show how a recently discovered black ring solution with a rotating 2-sphere can be turned into two new solutions of Einstein–Maxwell–dilaton theory. The first is a four-dimensional solution describing a pair of oppositely charged, extremal black holes—known as a black dihole—undergoing uniform acceleration. The second is a five-dimensional solution describing a pair of concentric, static ext...
متن کاملMassless string theory black holes as black diholes and quadruholes.
Massless black holes can be understood as bound states of a (positive-mass) extreme a p 3 black hole and a singular object with opposite (i.e., negative) mass with vanishing Arnowitt-Deser-Misner (total) mass but nonvanishing gravitational field. Supersymmetric balance of forces is crucial for the existence of this kind of bound states and explains why the system does not move at the speed of...
