“…Consequently, it offers a technique to incorporate the quantum gravity effect. The concept of minimum measurable length has considerable application to the physics of black hole [64][65][66][67][68][69][70]. These objects in the universe are important for classical and quantum gravity.…”

In this manuscript, we delve into an analytic and numerical probe of shadow with different accretion models, quasinormal modes, Hawking radiation, and gravitational lensing to study observational impacts of quantum effect introduced through linear-quadratic GUP(LQG). Our investigation reveals that the shadows of LQG-modified black holes are smaller and brighter than Schwarzschild black holes. To examine the impact of the quantum correction on the quasinormal mode, linear-quadratic GUP-modified black holes are explored under scalar and electromagnetic field perturbation. Here, linear-quadratic GUP is used to capture quantum corrections. It is observed that the incorporation of quantum correction by linear-quadratic GUP alters the singularity structure of the black hole. To compute the quasinormal modes of this linear-quadratic GUP-inspired quantum-corrected black holes, we compute the effective potential generated under the perturbation of scalar and electromagnetic field, and then we use the sixth-order WKB approach in conjunction with the appropriate numerical analysis. We find that the greybody factor decreases with the GUP parameter α implying that the probability of transmission decreases with the GUP parameter. The total power emitted by LQG modified black hole is found to be greater than that emitted by Schwarzschild black hole. Finally, we study weak gravitational lensing and make a comparison with quadratic GUP and linear GUP-modified black holes.

“…People have also modified the traditional Heisenberg uncertainty principle, which contradicts the existence of a minimum length, and proposed the generalized uncertainty principle (GUP). After its proposal, the GUP was quickly applied to various areas of physics such as gravitational corrections for quantum systems [7][8][9][10], corrections to the thermodynamics of black holes [11][12][13][14][15][16][17], and cosmology [18,19]. Additionally, the positive and negative GUP parameters have sparked numerous discussions: rainbow gravity corrections to the black hole information flux and Hawking radiation sparsity [20], the modification of special relativity [21], and the negative parameter of the GUP to recover the Chandrasekhar's limit [22], etc., argue that the negative parameter is applicable to a specific model.…”

In recent years, researchers have investigated the evaporation of Schwarzschild black holes using various forms of the generalized uncertainty principle (GUP), metric quantum correction, and non-commutative geometry, respectively. However, there are differences between the GUP correction and the other two methods in terms of describing the later stages of black hole evaporation. Furthermore, some studies argue that the GUP with a negative parameter cannot effectively correct for black hole evaporation, while others contend that the positivity or negativity of the GUP parameters should not affect the correction results. Taking the above into consideration, we reconsider black hole evaporation with the generalized uncertainty principle including a linear term (LGUP), and examine the case of negative parameters. The results indicate that the evaporation behavior of both Schwarzschild black holes and Reissner-Nordström black holes, under LGUP correction, is consistent with the results of metric quantum correction and non-commutative geometry. Additionally, the negative parameter LGUP can also effectively correct for black hole evaporation.
