Effective line elements and black-hole models in canonical loop quantum gravity [PDF]
Physical Review D, 2018 Canonical quantization is often used to suggest new effects in quantum gravity, in the dynamics as well as the structure of space-time. Usually, possible phenomena are first seen in a modified version of the classical dynamics, for instance in an ...

Shadow and stability of quantum-corrected black holes
European Physical Journal C: Particles and Fields, 2023 Recently the quantum Oppenheimer–Snyder gravitational collapse model has been proposed in loop quantum gravity, providing quantum-corrected Schwarzschild spacetimes as the exterior of the collapsing dust ball.

Gravitational Thermodynamics of Space-time Foam in One-loop Approximation [PDF]
, 1999 We show from one-loop quantum gravity and statistical thermodynamics that the thermodynamics of quantum foam in flat space-time and Schwarzschild space-time is exactly the same as that of Hawking-Unruh radiation in thermal equilibrium. This means we show

Effective dynamics from coherent state path integral of full loop quantum gravity [PDF]
Physical Review D, 2019 A new routine is proposed to relate loop quantum cosmology (LQC) to loop quantum gravity (LQG) from the perspective of effective dynamics. We derive the big-bang singularity resolution and big bounce from the first principle of full canonical LQG.

Information loss, made worse by quantum gravity?
Frontiers in Physics, 2015 Quantum gravity is often expected to solve both the singularity problem and the information-loss problem of black holes. This article presents an example from loop quantum gravity in which the singularity problem is solved in such a way that the ...

Loop-Quantum-Gravity Vertex Amplitude [PDF]
Physical Review Letters, 2007 Spinfoam theories are hoped to provide the dynamics of non-perturbative loop quantum gravity. But a number of their features remain elusive. The best studied one -the euclidean Barrett-Crane model- does not have the boundary state space needed for this, and there are recent indications that, consequently, it may fail to yield the correct low-energy $n$-

Perspectives on the dynamics in a loop quantum gravity effective description of black hole interiors [PDF]
Physical Review D, 2019 In the loop quantum gravity context, there have been numerous proposals to quantize the reduced phase space of a black hole, and develop a classical effective description for its interior which eventually resolves the singularity.
