We investigate the generalized uncertainty principle (GUP) corrections to the entropy content and the information flux of black holes, as well as the corrections to the sparsity of the Hawking radiation at the late stages of evaporation. We find that due to these quantum gravity motivated corrections, the entropy flow per particle reduces its value on the approach to the Planck scale due to a better accuracy in counting the number of microstates. We also show that the radiation flow is no…

Nonextensive black hole entropy and quantum gravity effects at the last stages of evaporation
It is shown that when introducing GUP effects, both R\'enyi entropy and temperature associated with black holes have finite values at the end of the evaporation process.
Minimal length and the flow of entropy from black holes
The existence of a minimal length, predicted by different theories of quantum gravity, can be phenomenologically described in terms of a generalized uncertainty principle. We consider the impact of
Analysis of black hole thermodynamics with a new higher order generalized uncertainty principle
This research explores a unified expression for the black hole thermodynamics in the presence of a special generalized uncertainty principle (GUP). We have considered a heuristic analysis versus
Black hole thermodynamics under the generalized uncertainty principle and doubly special relativity
We investigate the effect of the generalized uncertainty principle on the thermodynamic properties of the topological charged black hole in anti-de Sitter space within the framework of doubly

A bstractWe study a form of generalized uncertainty principle (GUP) that leads to vanishing quantum effect, i.e. ΔxΔp ~ 0, at sufficiently high momenta. We find that such a GUP allows black holes to
Sparsity of Hawking radiation in D + 1 space-time dimensions for massless and massive particles
Hawking radiation from an evaporating black hole has often been compared to black body radiation. However, this comparison misses an important feature of Hawking radiation: its low density of states.
Generalized uncertainty principle and black hole thermodynamics
Banerjee-Ghosh's work shows that the singularity problem can be naturally avoided by the fact that black hole evaporation stops when the remnant mass is greater than the critical mass when including


Entropy/Information flux in Hawking radiation
The key technical aspect of the calculation is a variant of the “average subsystem” approach developed by Page, which extends beyond bipartite pure systems, to a tripartite pure system that considers the influence of the environment.
The Generalized Uncertainty Principle and Black Hole Remnants
In the current standard viewpoint small black holes are believed to emit black body radiation at the Hawking temperature, at least until they approach Planck size, after which their fate is open to

This work argues that for a (macroscopically) Schwarzschild black hole this ensemble is formed by horizons with the same area, and obtains a statistical entropy proportional to the area, as in the Bekenstein-Hawking formula.
Black Hole Corrections due to Minimal Length and Modified Dispersion Relation
The generalized uncertainty principles (GUP) and modified dispersion relations (MDR) are much like two faces for one coin in research for the phenomenology of quantum gravity which apparently plays
When conceptual worlds collide: The generalized uncertainty principle and the Bekenstein-Hawking entropy
Recently, there has been much attention devoted to resolving the quantum corrections to the Bekenstein-Hawking (black hole) entropy. In particular, many researchers have expressed a vested interest
Massive vector particles tunneling from noncommutative charged black holes and their GUP-corrected thermodynamics
Abstract.In this paper, we investigate the tunneling process of charged massive bosons $ W^{\pm}$ (spin-1 particles) from noncommutative charged black holes such as charged RN black holes and charged
Hawking evaporation cascade in the presence of backreaction effect
We study the cascade of Hawking emission spectrum from the event horizon in the presence of one loop backreaction effect in a black hole background. The space–time taken here is the modified
