Physical properties of deflection angle and tunnelling radiation in the quantum-corrected black hole
We examine strong gravitational lensing in quantum-corrected spacetimes in fundamental general relativity models. Using the metric coefficients, it can be shown that photon circles for light rays that are correction parameter with the spacetime are present in quantum-corrected BH. The characteristic that distinguished quantum-corrected BH is the presence of stable circular orbits at every radial distance. To obtain effective potential, we employ the 4-velocity normalization condition for a time like geodesics and see the observer's initial position from which the light ray originates. Based on their strong field gravitational lensing characteristics, we suggest a Bozza strategy to field limit by expanding the photon's deflection angle. This expansion is calculated for an entirely generic quantum-corrected spacetime, assuming that the light ray obeys the geodesics equation without using the field equations and that the minimum impact parameter is attained. A semi-classical algorithm investigates the particles tunneling from a quantum-corrected BH. The generic tunneling spectrum of scattered particles is derived, disregarding interaction and self-gravitational impacts. We examine the quantum-corrected BH temperature with incorporation, and we also note the existence of the first-order modification.
