Self-action of electromagnetic charge in a wormhole with an infinitely short throat

TL;DR

This paper calculates the electromagnetic self-force on a charge in a wormhole spacetime with an infinitely short throat, considering a non-minimal coupling between the electromagnetic field and curvature.

Contribution

It introduces a model for electromagnetic self-force in a wormhole with non-minimal curvature coupling, focusing on an infinitely short throat geometry.

Findings

Self-force depends on non-minimal coupling parameters.

Explicit expression for the self-force in the wormhole spacetime.

Analysis of how wormhole geometry influences electromagnetic interactions.

Abstract

The self-force of the electromagnetic charge in the space-time of a wormhole with an infinitely short throat is calculated. It is assumed that the charge is a source of an electromagnetic field that is in non-minimal connection with the curvature of space-time.
