Probing global aspects of a geometry by the self-force on a charge: Cylindrical thin-shell wormholes
We obtain the self-interaction for a point charge in the space-time of a cylindrical thin-shell wormhole connecting two identical locally flat geometries with a constant deficit angle. Although this wormhole geometry is locally indistinguishable from a cosmic string background, the corresponding sel...
