Abstract

Gravitating stationary dyons and rotating vortex rings

We discuss dyons and electrically charged monopole-antimonopole pairs and vortex rings in Einstein-Yang-Mills-Higgs theory. The solutions are stationary, axially symmetric and asymptotically flat. In monopole-antimonopole pair solutions the Higgs field vanishes at two discrete points along the symmetry axis. In vortex solutions the Higgs field vanishes on a ring, centered around the symmetry axis. The dyons represent non-static solutions with vanishing angular momentum. In contrast to the dyons the monopole-antimonopole pairs and vortex rings possess vanishing magnetic charge, but finite angular momentum, equaling n times their electric charge. The dependence of the solutions on the strength of gravity and the Higgs self-interaction is studied.
