A TorsionInduced Electric Charge of the Abelian Higgs Sunspot
Abstract
One demonstrates that the Abelian Higgs sunspot acquires a nonzeroelectric charge (as well as angular momentum) in the background of a curved spacetime endowed with a constant, completely antisymmetrictorsion tensor. An ‘effective’ Lagrangian density is shown to contain a ChernSimonslike term, and it leads to gaugeinvariant equations of motion provided that one can neglect terms of the second order in a torsion's magnitude. The spacetime torsion is also revealed to lock together the spot'selectric andmagnetic degrees of freedom.
