“…However, to understand the inside of the Black hole and the Big Bang, these theories should be combined and the quantum corrections must be located in the Schwarzschild solution according to the various approaches to unify them. Kazakov and Solodukhin show that the generalization of the Schwarzschild solution is possible by neglecting the non-spherical deformations using the effective scalar-tensor gravity [5] and its properties are studied in [6][7][8]. Furthermore gravitational lensing (GL) is one of the famous prediction and numerous individuals also verified these experiments [9,10].…”

In this paper, we study light rays in a Kazakov-Solodukhin black hole. To this end, we use the optical geometry of the Kazakov-Solodukhin black hole within the Gauss-bonnet theorem. We first show the effect of the deformation parameter a on the Gaussian optical curvature, and then we use the modern method popularized by Gibbons and Werner to calculate the weak deflection angle of light. Our calculations of deflection angle show how gravitational lensing is affected by the deformation parameter a. Moreover, we demonstrate the effect of a plasma medium on weak gravitational lensing by the Kazakov-Solodukhin black hole. We discuss that the increasing the deformation parameter a, will increase the weak deflection angle of the black hole. Our analysis also uncloak how one may find a observational evidence for a deformation parameter on the deflection angle. In addition, we studied the rigorous bounds of the Kazakov-Solodukhin black hole for the grey body factor and also studied the graphical behaviour of the bounds by fixing l = 0 and M = 1 and observed that increasing the deformation parameter a will decrease the rigorous bound T b of the black hole.

“…And in [15] the authors have explored the Hawking radiation from the quantumcorrected Schwarzschild black hole via the tunneling process. In addition, thermodynamic properties have been considered in [16][17][18][19]. In addition, a regular black hole solution can also be obtained by assuming a non-commutative spacetime.…”

We consider quantum corrections for the Schwarzschild black hole metric by using the generalized uncertainty principle (GUP) to investigate quasinormal modes, shadow and their relationship in the eikonal limit. We calculate the quasinormal frequencies of the quantum-corrected Schwarzschild black hole by using the sixth-order Wentzel-Kramers-Brillouin (WKB) approximation, and also perform a numerical analysis that confirms the results obtained from this approach. We also find that the shadow radius is nonzero even at very small mass limit for finite GUP parameter.

In this paper, we study light rays in a Kazakov-Solodukhin black hole. To this end, we use the optical geometry of the Kazakov-Solodukhin black hole within the Gauss-bonnet theorem. We first show the effect of the deformation parameter $a$ on the Gaussian optical curvature, and then we use the modern method popularized by Gibbons and Werner to calculate the weak deflection angle of light. Our calculations of deflection angle show how gravitational lensing is affected by the deformation parameter $a$. Moreover, we demonstrate the effect of a plasma medium on weak gravitational lensing by the Kazakov-Solodukhin black hole. We discuss that the increasing the deformation parameter $a$, will increase the weak deflection angle of the black hole.
