Thermal analysis with emission energy of perturbed black hole in f(Q) gravity

Abstract

In the present paper, we investigate the thermodynamics of a new perturbed black hole solution in symmetric teleparallel gravity. Our main focus is on the solution for a nonlinear model like Q+αQ2. We study new features of null geodesics and quasi-normal modes that occur for the current perturbed black hole solution. We inspect the critical behavior of thermal fluctuation and phase transitions in the background of a considered black hole solution and get the Davies points. To complete this study, we also explore the interesting aspects of the emission energy and quantum fluctuations. We highlight that our results are in good agreement with the thermodynamics of the previous black hole solutions and assumptions presented in the literature.
