# Superradiant stability of Mutated Reissner-Nordstr\"{o}m black holes

## TL;DR

This paper investigates the superradiant stability of a novel mutated Reissner-Nordström black hole, generated by scalar hair, showing it remains stable against superradiant perturbations regardless of the scalar field's mass.

## Contribution

It introduces a new class of mutated black holes with scalar hair and demonstrates their stability against superradiance, expanding understanding of black hole stability in modified spacetimes.

## Key findings

- The mutated black holes are stable against superradiance for all tested scalar masses.
- Scalar hair can generate black holes with properties similar to wormholes.
- Superradiant instability is not present in these mutated black hole spacetimes.

## Abstract

A scalar hair is used to generate a mutated black hole, which mimics an Einstein-Rosen bridge or a wormhole. The superradiant stability of the spacetime is studied under perturbation by an electrically charged massive scalar field. The system appears to be stable against superradiance irrespective of the mass of the test field.
