A paradigm describing black hole evaporation in non-perturbative quantum gravity is developed by combining two sets of detailed results: (i) resolution of the Schwarzschild singularity using quantum geometry methods and (ii) time evolution of black holes in the trapping and dynamical horizon frameworks. Quantum geometry effects introduce a major modification in the traditional spacetime diagram of black hole evaporation, providing a possible mechanism for recovery of information that is…

Spacetime structure of an evaporating black hole in quantum gravity
The impact of the leading quantum gravity effects on the dynamics of the Hawking evaporation process of a black hole is investigated. Its spacetime structure is described by a renormalization group…
Black hole radiation spectrum in loop quantum gravity: isolated horizon framework
Recent detailed analysis within the loop quantum gravity calculation of black hole entropy shows a stair-like structure in the behavior of entropy as a function of horizon area. The non-trivial…
Black to white hole tunneling: An exact classical solution
We present a metric that describes conventional matter collapsing into a black hole, bouncing and emerging from a white hole, and that satisfies the vacuum Einstein equations everywhere, including in…
Quantum-gravity effects outside the horizon spark black to white hole tunneling
We show that there is a classical metric satisfying the Einstein equations outside a finite spacetime region where matter collapses into a black hole and then emerges from a white hole. We compute…
Black holes and entropy in loop quantum gravity: An Overview
Black holes in equilibrium and the counting of their entropy within Loop Quantum Gravity are reviewed. In particular, we focus on the conceptual setting of the formalism, briey summarizing the main…
Phenomenological loop quantum geometry of the Schwarzschild black hole

Quantum fields in the background spacetime of a polymeric loop black hole
The description of black holes in loop quantum gravity is a hard and tricky task. In this article, we focus on a minisuperspace approach based on a polymerization procedure. We consider the resulting…

We construct a formalism for evolving spherically symmetric black hole initial data sets within a canonical approach to quantum gravity. This problem can be formulated precisely in quantum reduced…
Effective quantum dust collapse via surface matching
The fate of matter forming a black hole is still an open problem, although models of quantum gravity corrected black holes are available. In loop quantum gravity (LQG) models were presented, which…
A linear approximation to black hole evaporation
An evaporating Schwarzschild black hole is analysed including back reaction in a linear approximation. The analysis assumes a massless scalar field propagating in a spacetime consisting of two Vaidya…

Black hole evaporation without information loss
An approach to black hole quantization is proposed wherein it is assumed that quantum coherence is preserved. After giving our motivations for such a quantization procedure we formulate the…
Evanescent black holes.
TLDR
A renormalizable theory of quantum gravity coupled to a dilaton and conformal matter in two spacetime dimensions is analyzed and suggests that the collapsing matter radiates away all of its energy before an event horizon has a chance to form, and black holes disappear from the quantum-mechanical spectrum.
Unitary theory of evaporating two-dimensional black holes
We study a manifestly unitary formulation of two-dimensional dilaton quantum gravity based on the reduced phase space quantization. The spacetime metric operator can be expanded in a formal power…
