TL;DR

This paper explores rotating wormholes immersed in bosonic matter, highlighting how scalar fields induce rotation and asymmetry, and revealing new structures like double-throat wormholes.

Contribution

It demonstrates that bosonic scalar fields can induce rotation and asymmetry in wormholes, and introduces the concept of double-throat wormholes with rotating matter.

Findings

Scalar fields induce rotation of the wormhole throat.

Asymmetry in matter distribution leads to asymmetric wormholes.

Rotating matter enables the existence of double-throat wormholes.

Abstract

We consider four-dimensional wormholes immersed in bosonic matter. While their existence is based on the presence of a phantom field, many of their interesting physical properties are bestowed upon them by an ordinary complex scalar field, which carries only a mass term, but no self-interactions. For instance, the rotation of the scalar field induces a rotation of the throat as well. Moreover, the bosonic matter need not be symmetrically distributed in both asymptotically flat regions, leading to symmetric and asymmetric rotating wormhole spacetimes. The presence of the rotating matter also allows for wormholes with a double throat.
