Black-hole models in loop quantum gravity

M Bojowald - Universe, 2020 - mdpi.com
Dynamical black-hole scenarios have been developed in loop quantum gravity in various

Stochastic gravitational-wave background in quantum gravity

G Calcagni, S Kuroyanagi - Journal of Cosmology and …, 2021 - iopscience.iop.org
Among all cosmological quantum-gravity or quantum-gravity-inspired scenarios, only very
few predict a blue-tilted primordial tensor spectrum. We explore five of them and check …

Polymer Schwarzschild black hole: An effective metric

JB Achour, F Lamy, H Liu, K Noui - Europhysics letters, 2018 - iopscience.iop.org
We consider the modified Einstein equations obtained in the framework of effective
spherically symmetric polymer models inspired by loop quantum gravity. When one takes …

Pre-inflationary universe in loop quantum cosmology

T Zhu, A Wang, G Cleaver, K Kirsten, Q Sheng - Physical Review D, 2017 - APS
The evolutions of the flat Friedmann-Lemaître-Robertson-Walker universe and its linear
perturbations are studied systematically in the dressed metric approach of loop quantum …

Hamiltonian formulation and loop quantization of a recent extension of the Kruskal spacetime

B Elizaga Navascués, A García-Quismondo… - Physical Review D, 2022 - APS
We study the Hamiltonian formulation of the Ashtekar-Olmedo-Singh model for the
description of the interior geometry of nonrotating, uncharged black holes. This model …

Loop quantum cosmology: From pre-inflationary dynamics to observations

A Ashtekar, A Barrau - Classical and Quantum Gravity, 2015 - iopscience.iop.org
