Self-Interactions in the Spacetime of a Scalar-Tensor Cosmic String
arXiv:hep-th/0410048 · doi:10.1016/j.physleta.2005.11.015
Abstract
We study the effect of the geometry and topology of a scalar-tensor cosmic string space-time on the electric and magnetic fields of line sources. It is shown that the dilatonic coupling of the gravity induces effects along the string comparable to a current flow allowing for forbidden regions near the string.
