Dyonic Kerr-Newman black holes, complex scalar field and Cosmic Censorship

TL;DR

This paper demonstrates through a thought experiment that interactions with a complex scalar field cannot turn an extremal Kerr-Newman black hole into a naked singularity, supporting the weak cosmic censorship conjecture.

Contribution

It provides a theoretical analysis showing that scalar field interactions do not violate cosmic censorship in Kerr-Newman black holes.

Findings

Interaction cannot create naked singularities from extremal black holes

Supports the weak cosmic censorship conjecture

Applicable to generic wave packet configurations

Abstract

We construct a gedanken experiment, in which a weak wave packet of the complex massive scalar field interacts with a four-parameter (mass, angular momentum, electric and magnetic charges) Kerr-Newman black hole. We show that this interaction cannot convert an extreme the black hole into a naked sigularity for any black hole parameters and any generic wave packet configuration. The analysis therefore provides support for the weak cosmic censorship conjecture.
