Thin-shell wormholes in Einstein-Maxwell theory with a Gauss-Bonnet term

TL;DR

This paper investigates five-dimensional thin-shell wormholes within Einstein-Maxwell theory augmented by a Gauss-Bonnet term, demonstrating that quadratic corrections enhance stability and reduce exotic matter needs.

Contribution

It introduces a detailed analysis of stability and matter requirements for wormholes in a higher-dimensional gravity model with quadratic curvature corrections.

Findings

Quadratic Gauss-Bonnet term widens stable configuration range.

Inclusion of the term reduces the amount of exotic matter needed.

Stability is improved compared to models without the Gauss-Bonnet correction.

Abstract

We study five dimensional thin-shell wormholes in Einstein-Maxwell theory with a Gauss-Bonnet term. The linearized stability under radial perturbations and the amount of exotic matter are analyzed as a function of the parameters of the model. We find that the inclusion of the quadratic correction substantially widens the range of possible stable configurations, and besides it allows for a reduction of the exotic matter required to construct the wormholes.
