Shadow and stability of quantum-corrected black holes

open access: yesEuropean 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]

open access: yes, 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

Perspectives on the dynamics in a loop quantum gravity effective description of black hole interiors [PDF]

open access: yesPhysical 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.

Information loss, made worse by quantum gravity?

open access: yesFrontiers 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 ...

Towards Cosmological Dynamics from Loop Quantum Gravity [PDF]

open access: yes, 2018
We present a systematic study of the cosmological dynamics resulting from an effective Hamiltonian, recently derived in loop quantum gravity (LQG) using Thiemann's regularization and earlier obtained in loop quantum cosmology (LQC) by keeping the ...

Polar gravitational perturbations and quasinormal modes of a loop quantum gravity black hole

open access: yes, 2020
In this work, we have calculated the polar gravitational quasinormal modes for a quantum corrected black hole model, that arises in the context of Loop Quantum Gravity, known as Self-Dual Black Hole.

Coherent intertwiner solution of simplicity constraint in all dimensional loop quantum gravity [PDF]

open access: yesPhysical Review D, 2019
We propose a new treatment of the quantum simplicity constraints appearing in the general ${SO(D+1)}$ formulation of loop quantum gravity for the ${(1+D)}$-dimensional space-time. Instead of strongly imposing the constraints, we construct a specific form
