TL;DR
This paper investigates the quasinormal modes of charged black holes in the Randall-Sundrum brane world, analyzing how electromagnetic and tidal charges, as well as bulk thickness, influence the oscillation spectrum.
Contribution
It introduces a third order WKB approximation to study scalar field quasinormal modes in charged brane world black holes, considering effects of charges and bulk properties.
Findings
Electromagnetic and tidal charges significantly affect quasinormal frequencies.
Bulk thickness influences the damping and oscillation frequencies.
The third order WKB method effectively models these effects.
Abstract
We study the quasinormal modes of the massless scalar field of charged black holes embedded in the Randal-Sundrum brane world using the third order WKB approximation. We consider the effects of the electromagnetic and tidal charges on quasinormal frequencies spectrum for charged black hole black holes as well as the effect of the thickness of the bulk.
