Static axionlike dark matter clouds around magnetized rotating wormholes -- probe limit case

TL;DR

This paper investigates the distribution of axionlike dark matter around rotating wormholes in the probe limit, highlighting differences from black hole environments through numerical analysis of two toy models.

Contribution

It introduces a numerical study of axionlike dark matter distribution around rotating wormholes, considering non-trivial coupling to electromagnetic fields in the probe limit.

Findings

Dark matter distribution differs from that near rotating black holes.

The study provides insights into axion behavior in wormhole spacetimes.

Differences depend on the wormhole models and magnetic field configurations.

Abstract

The problem of the distribution of axionlike particle, being the model of dark matter, in the nearby of rotating wormholes has been investigated numerically. In the model in question the axion scalar is non-trivially coupled to the Maxwell gauge field. We consider two toy models of rotating wormholes embedded in magnetic field, Kerr-like and Teo rotating wormholes. Moreover one assumes that the matter fields will not backreact on the wormhole spacetimes, i.e., we shall study the problem in the probe limit case. We point out the differences in the distribution of dark matter comparing to the location of it in the vicinity of rotating magnetized black holes.
