Black Rings, Vortons and Saturns: a `Dictionary´
Final Report Abstract
Within the frame of the project, we have achieved around two thirds of the defined goals. At the same time, a number of new unexpected results have been found beyond the proposed framework. We have managed to investigate vorton solutions in a systematic way. Moreover, for the first time in the literature, their gauged generalizations have been constructed. Beyond the purposes of the original project, the existence of stable vorton solutions was established. ‘Divorton’ solutions have been also explicitly constructed. Our results on vortons were achieved in Witten’s model but the derived configurations have a much wider scope of applications, stretching to condensed matter and cosmology. On the gravity side of the project, we have considered black rings in more than five dimensions, providing the first explicit non-perturbative construction of such configurations. Generalized black rings with a regular horizon and without conical singularities have also been found by considering a background magnetic field. Also, within this project, we have started to develop a consistent numerical scheme for the study of axially symmetric (gravitating-) solitons in an anti-de Sitter spacetime background. Beyond the original goals of the project, a number of important results in the physics of hairy black holes were obtained, in particular the existence of asymptotically flat, stable black holes with non-Abelian hair was established. Moreover, it was discovered that extremal black holes may possess radial excitations.
