Quasinormal modes and thermodynamic properties of GUP-corrected Schwarzschild black hole surrounded by quintessence

Abstract

We study the Quasinormal Modes (QNMs) of the Schwarzschild black hole surrounded by a quintessence field after implementing the quantum corrections to its solution as required by the Generalized Uncertainty Principle (GUP). We analyze the dependence of the QNMs on the deformation parameters of GUP as well as on the quintessence parameter. For better accuracy, we compare the results of the QNMs obtained via Mashhoon method with the semi-analytical WKB method. Further, we study the thermodynamic properties of the GUPcorrected Schwarzschild black hole and check for any dependence with the deformation parameters and the quintessence parameter. In particular, we compute the Hawking temperature, heat capacity and entropy for the black hole and analyze the results graphically to show the dependency of the thermodynamic properties on the deformation parameters as well as the quintessence parameter. Black hole remnant has been studied and it is shown that the possible existence of remnant radius as well as remnant temperature depends on the deformations introduced. However, it is observed that the GUP-corrected black hole constructed here can not become a remnant. Black hole shadow has been investigated and it was found that the shadow has linear relations with the model parameters. We conclude the work with a summary note and future possibilities.

Absorption, scattering and shadow by a noncommutative black hole with global monopole

“…In the present work, we have the main purpose of exploring the effect of quantum gravity corrections that contribute to the process of massless scalar wave scattering by a noncommutative black hole with a global monopole. The problem of scattering a massless scalar wave across a black hole has been constantly studied by several authors [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], and many works considering the low frequency limit (G M 1) can be found in the literature [36][37][38][39][40][41][42][43][44][45][46][47]. The use of the partial wave method can also be found in several different contexts [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62].…”

Generalized Extended Uncertainty Principle Black Holes: Shadow and Lensing in the Macro- and Microscopic Realms

“…In 1979, Luminet gave the formula for the angular radius of the shadow [36]. Then several studies have explored the shadows of quantum black holes [37][38][39][40][41][42][43][44]. In this paper, we are also interested in probing the GEUP effects using the strong and weak deflection angles.…”
