Self-force of a point charge in the space-time of a symmetric wormhole

Understand

We consider the self-energy and the self-force for an electrically charged particle at rest in the wormhole space-time.

• We develop general approach and apply it to two specific profiles of the wormhole throat with singular and with smooth curvature.
• The self-force for these two profiles is found in manifest form; it is an attractive force.
• We also find an expression for the self-force in the case of arbitrary symmetric throat profile.
