Wormholes Immersed in Rotating Matter

TL;DR

This paper introduces a new class of rotating wormholes immersed in rotating matter, revealing their geometric structures, ergoregions, and light ring configurations, expanding understanding of wormhole physics.

Contribution

It demonstrates that rotating matter induces rotation in Ellis wormholes, enabling symmetric, rotating wormholes with variable throat structures and detailed analysis of their properties.

Findings

Rotation of matter causes the wormhole throat to rotate.

Wormhole geometry can transition from single to double throat.

The structure of ergoregions and light rings is characterized.

Abstract

We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asymptotically flat spacetime regions. We analyze the properties of this new type of rotating wormholes and show that the wormhole geometry can change from a single throat to a double throat configuration. We further discuss the ergoregions and the lightring structure of these wormholes.
