Are slowly rotating Ellis-Bronnikov wormholes stable?

TL;DR

This paper explores how slow rotation may stabilize Ellis-Bronnikov wormholes, suggesting rotation could make certain traversable wormholes linearly stable, which is significant for their theoretical viability.

Contribution

It demonstrates that slow rotation can potentially stabilize Ellis-Bronnikov wormholes, a novel insight into wormhole stability in General Relativity.

Abstract

We investigate the radial perturbations of Ellis-Bronnikov wormholes ($\mathrm{l}=0$) in a slowly rotating background expanded up to second order in rotation. We find indications that simple wormhole solutions such as Ellis-Bronnikov in General Relativity can be stabilized by rotation, thus favoring a viable traversable wormhole. This opens up the intriguing question whether the many other wormhole solutions with or without the support of exotic matter can become linearly mode stable when the wormhole rotates.
