“…It has been observed that the GUP reveals a self-complete characteristic of gravity which basically amounts to hiding any curvature singularity behind an event horizon as a consequence of matter compression at the Planck scale [39][40][41]. Further, the effects of the GUP have also been considered in the tunneling formalism for Hawking radiation to evaluate the quantum-corrected Hawking temperature and entropy of a Schwarzschild black hole [42][43][44][45][46]. In our earlier 2 Advances in High Energy Physics findings [32][33][34][35][36], we have studied the modification of thermodynamic properties, namely, the temperature, heat capacity, and entropy of black holes due to the simplest form of the GUP.…”

We study the modification of thermodynamic properties of Schwarzschild and Reissner-Nordström black hole in the framework of generalized uncertainty principle with correction terms up to fourth order in momentum uncertainty. The mass-temperature relation and the heat capacity for these black holes have been investigated. These have been used to obtain the critical and remnant masses. The entropy expression using this generalized uncertainty principle reveals the area law up to leading order logarithmic corrections and subleading corrections of the form 1/ . The mass output and radiation rate using Stefan-Boltzmann law have been computed which show deviations from the standard case and the case with the simplest form for the generalized uncertainty principle.

“…modes of evaporation [59][60][61]. In this setup, information leaks out of the BH in the form of non-thermal GUP correlations and, on the other hand, the inclusion of quantum gravity effects as the GUP expression can halt the evaporation process, so that a stable BH remnant is left behind, including a part of the BH information content (see also [46]).…”

We derive the mass term of the Bardeen metric in the presence of a noncommutative geometry induced minimal length. In this setup, the proposal of a stable black hole remnant as a candidate to store information is confirmed. We consider the possibility of having an extremal configuration with one degenerate event horizon and compare different sizes of black hole remnants. As a result, once the magnetic charge g of the noncommutative Bardeen solution becomes larger, both the minimal nonzero mass M 0 and the minimal nonzero horizon radius r 0 get larger. This means, subsequently, under the condition of an adequate amount of g, the three parameters g, M 0 , and r 0 are in a connection with each other linearly. According to our results, a noncommutative Bardeen black hole is colder than the noncommutative Schwarzschild black hole and its remnant is bigger, so the minimum required energy for the formation of such a black hole at particle colliders will be larger. We also find a closely similar result for the Hayward solution.

“…In this way, additional investigations taking into account quantum gravity contributions to the black hole emission process have been done by considering noncommutative geometry, Generalized Uncertainty Principle (GUP), as well as Loop Quantum Gravity (LQG) and string theory scenarios [28][29][30][31][32][33][34][35][36][37], where the information loss issue has also been considered.…”
