d-dimensional non-asymptotically flat thin-shell wormholes in Einstein-Yang-Mills-Dilaton gravity

TL;DR

This paper constructs stable, non-asymptotically flat thin-shell wormholes in d-dimensional Einstein-Yang-Mills-Dilaton gravity supported by exotic matter, highlighting the role of the dilaton field in spacetime properties.

Contribution

It demonstrates the existence of stable thin-shell wormholes in EYMD gravity with non-asymptotic flatness due to the dilaton, expanding understanding of wormhole solutions in higher-dimensional theories.

Findings

Stable thin-shell wormholes are supported by exotic matter.

Dilaton field induces non-asymptotic flatness in spacetime.

Wormholes constructed from EYMD black hole solutions are stable.

Abstract

Thin-shell wormholes in Einstein-Yang-Mills-dilaton (EYMD) gravity are considered. We show that a non-asymptotically flat (NAF) black hole solution of the d-dimensional EYMD theory provides stable thin-shell wormholes which are supported entirely by exotic matter. The presence of dilaton makes the spacetime naturally NAF, and with our conclusion it remains still open to construct wormholes supported by normal matter between two such spacetimes.
