Thin-shell wormholes with a generalized Chaplygin gas in Einstein-Born-Infeld theory

TL;DR

This paper constructs and analyzes the stability of spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas within Einstein-Born-Infeld theory, comparing results with Maxwell electrodynamics.

Contribution

It introduces a new model of thin-shell wormholes in Einstein-Born-Infeld theory and studies their stability, highlighting how the Born-Infeld parameter affects stability regions.

Findings

Stability regions decrease with larger Born-Infeld parameter values.

Wormholes become less stable as the theory departs from Maxwell electrodynamics.

Comparison with Maxwell case shows significant differences in stability conditions.

Abstract

We construct spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas in Born-Infeld electrodynamics coupled to Einstein gravity, and we analyze their stability under radial perturbations. For different values of the Born-Infeld parameter and the charge, we compare the results with those obtained in a previous work for Maxwell electrodynamics. The stability region in the parameter space reduces and then disappears as the value of the Born-Infeld parameter is modified in the sense of a larger departure from Maxwell theory.
