Physical Properties of Brane-World Black Hole Solutions via a Confining Potential

Abstract

In this paper, we consider two brane-world black holes whose solutions are obtained via a confining potential and study their thermodynamical properties. The modified entropies by taking account of the generalized uncertainty principle (GUP) are obtained. We also determine the scalar effective potentials in order to compute the greybody factors of zero-spin particles (bosons) for both geometries. Finally, using the sixth-order WKB approach, quasi-normal modes (QNMs), which are also known as black hole fingerprints, are derived concerning the brane-world black hole parameters. The results obtained are graphically depicted, tabulated, and interpreted.

Fermionic and Bosonic Greybody Factors as well as Quasinormal Modes for Charged Taub NUT Black Holes

“…BHs caused by fields of a different nature like spin-0, 1, 1/2.. fields [19]. Those works led to the developments of QNM and GF methods [20][21][22][23][24]. Ultimately, scientists obtained important information regarding the stability and thermal radiation of BHs against perturbations occuring in the exterior region.…”
