Massive Charged Scalar Quasinormal Modes of Reissner-N\"ordstrom Black Hole Surrounded by Quintessence

TL;DR

This paper investigates how a surrounding quintessence field affects the quasinormal modes of massive charged scalar perturbations around a Reissner-Nordstrom black hole, revealing slower damping due to quintessence.

Contribution

It provides the first detailed analysis of quasinormal frequencies in a black hole spacetime influenced by quintessence using third order WKB approximation.

Findings

Quasinormal frequencies damp more slowly with quintessence presence.

Frequency variations depend on black hole charge, scalar field charge, and mass.

Quintessence alters the damping rates of scalar perturbations.

Abstract

We evaluate the complex frequencies of the normal modes for the massive charged scalar field perturbations around a Reissner-N\"ordstrom black hole surrounded by a static and spherically symmetric quintessence using third order WKB approximation approach. Due to the presence of quintessence, quasinormal frequencies damp more slowly. We studied the variation of quasinormal frequencies with charge of the black bole, mass and charge of perturbating scalar field and the quintessential state parameter.
