Linearized stability of charged thin-shell wormholes

TL;DR

This paper investigates the stability of charged thin-shell wormholes under symmetric perturbations, demonstrating that higher charge levels enhance stability by relaxing constraints on the equation of state.

Contribution

It introduces an analysis showing that large charge values stabilize thin-shell wormholes, reducing the restrictions on their equations of state compared to uncharged cases.

Findings

Large charge values improve wormhole stability.

Charged wormholes have less restrictive stability constraints.

Stability depends on the charge magnitude.

Abstract

The linearized stability of charged thin shell wormholes under spherically symmetric perturbations is analized. It is shown that the presence of a large value of charge provides stabilization to the system, in the sense that the constrains onto the equation of state are less severe than for non-charged wormholes.
