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 ...

Gravitational Lensing Effects from Models of Loop Quantum Gravity with Rigorous Quantum Parameters
UniverseMany previous works have studied gravitational lensing effects from Loop Quantum Gravity. So far, gravitational lensing effects from Loop Quantum Gravity have only been studied by choosing large quantum parameters much larger than the Planck scale ...

The Quantum Configuration Space of Loop Quantum Cosmology
, 2007 The article gives an account of several aspects of the space known as the Bohr compactification of the line, featuring as the quantum configuration space in loop quantum cosmology, as well as of the corresponding configuration space realization of the so-

A Brief Introduction to Loop Quantum Cosmology [PDF]
, 2009 In recent years, Loop Quantum Gravity has emerged as a solid candidate for a nonperturbative quantum theory of General Relativity. It is a background independent theory based on a description of the gravitational field in terms of holonomies and fluxes ...

Quantum reduced loop gravity and the foundation of loop quantum cosmology [PDF]
International Journal of Modern Physics D, 2016 Quantum reduced loop gravity is a promising framework for linking loop quantum gravity and the effective semiclassical dynamics of loop quantum cosmology. We review its basic achievements and its main perspectives, outlining how it provides a quantum description of the Universe in terms of a cuboidal graph which constitutes the proper framework for ...

(b,v)-type variables for black to white hole transitions in effective loop quantum gravity
Physics Letters B, 2021 Quantum gravity effects in effective models of loop quantum gravity, such as loop quantum cosmology, are encoded in the choice of so-called polymerisation schemes.

, 1993 The loop representation plays an important role in canonical quantum gravity because loop variables allow a natural treatment of the constraints. In these lectures we give an elementary introduction to (i) the relevant history of loops in knot theory and

Loop quantization of the Schwarzschild black hole [PDF]
, 2013 We quantize spherically symmetric vacuum gravity without gauge fixing the diffeomorphism constraint. Through a rescaling, we make the algebra of Hamiltonian constraints Abelian and therefore the constraint algebra is a true Lie algebra.
