Stability Analysis of Thin-Shell Wormholes from Charged Black String

TL;DR

This paper constructs and analyzes the stability of thin-shell wormholes derived from charged black strings, considering exotic matter and linear perturbations, revealing both stable and unstable configurations.

Contribution

It introduces a method to build thin-shell wormholes from charged black strings using cut-and-paste, and examines their stability with modified generalized Chaplygin gas.

Findings

Stable and unstable configurations are both possible.

Stability depends on specific parameters and perturbation conditions.

The analysis provides insights into the conditions for wormhole stability.

Abstract

In this paper, we construct thin-shell wormholes from charged black string through cut and paste procedure and investigate its stability. We assume modified generalized Chaplygin gas as a dark energy fluid (exotic matter) present in the thin layer of matter-shell. The stability of these constructed thin-shell wormholes is investigated in the scenario of linear perturbations. We conclude that static stable as well as unstable configurations are possible for cylindrical thin-shell wormholes.
