We present a review on some of the basic aspects concerning quantum cosmology in the
presence of cut-off physics as it has emerged in the literature during the last fifteen years …

Quantum cosmology has traditionally been studied at the level of symmetry-reduced
minisuperspace models, analyzing the behavior of wave functions. However, in the absence …

This article presents a new model-independent constraint for bouncing black hole
geometries. This constraint, applicable for a physical black hole formed by a collapsing …

We continue our analysis of a quantum cosmology model describing a flat Friedmann–
Lemaître–Robertson–Walker Universe filled with a (free) massless scalar field and an …

Ay! There are times when the great universe Like cloth in some unskilful dyers' vat Shrivels
into a hand's-breadth, and perchance That time is now! Well! Let that time be now. Let this …

Canonical methods can be used to construct effective actions from deformed covariance
algebras, as implied by quantum-geometry corrections of loop quantum gravity. To this end …

A key result of isotropic loop quantum cosmology is the existence of a quantum bounce
which occurs when the energy density of the matter field approaches a universal maximum …

We investigate the quasinormal mode (QNM) spectra for scalar and electromagnetic fields
over a covariant loop quantum gravity (LQG) black hole. For the fundamental modes, the …

This article lays out a complete framework for an effective theory of cosmological
perturbations with corrections from canonical quantum gravity. Since several examples exist …

A quantum analysis of the vacuum Bianchi IX model is performed, focusing in particular on
the chaotic nature of the system. The framework constructed here is general enough for the …
