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