Traversable wormholes in a string cloud

TL;DR

This paper investigates the properties, stability, and matter requirements of traversable wormholes within a string cloud background, providing insights into their physical viability and potential extensions.

Contribution

It introduces a detailed analysis of thin-shell wormholes in a string cloud, including stability and exotic matter assessments, with non-perturbative dynamics and model extensions.

Findings

Exotic matter requirements depend on model parameters.

Wormholes can be stable under radial perturbations.

Traversability conditions are established for the model.

Abstract

We study spherically symmetric thin-shell wormholes in a string cloud background in (3+1)-dimensional spacetime. The amount of exotic matter required for the construction, the traversability and the stability under radial perturbations, are analyzed as functions of the parameters of the model. Besides, in the Appendices a non perturbative approach to the dynamics and a possible extension of the analysis to a related model are briefly discussed.
