Chiral String in a Curved Space: Gravitational Self-Action

TL;DR

This paper investigates the gravitational self-action of classical superconducting strings in curved spacetime, showing that the divergent part of the effective action vanishes for both Nambu-Goto and chiral strings.

Contribution

It demonstrates that the divergent component of the effective action is zero for these string models, advancing understanding of their self-interaction in curved backgrounds.

Findings

Divergent part of the effective action is zero for Nambu-Goto strings.

Divergent part of the effective action is zero for chiral superconducting strings.

Provides insights into gravitational self-interaction of strings in curved spacetime.

Abstract

We analyze the effective action describing the linearised gravitational self-action for a classical superconducting string in a curved spacetime. It is shown that the divergent part of the effective action is equal to zero for the both Nambu-Goto and chiral superconducting string.
