This article reviews the present status of the spin-foam approach to the quantization of
gravity. Special attention is payed to the pedagogical presentation of the recently-introduced …

I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

A bstract In this second paper of the series we continue to spell out a new program for
quantum gravity, grounded in the notion of corner symmetry algebra and its representations …

The detection of variations of fundamental constants of the Standard Model would provide
us with compelling evidence of new physics, and could lift the veil on the nature of dark …

This is a review of results on black hole physics in the context of loop quantum gravity. The
key feature underlying these results is the discreteness of geometric quantities at the Planck …

A bstract In the tetrad formulation of gravity, the so-called simplicity constraints play a central
role. They appear in the Hamiltonian analysis of the theory, and in the Lagrangian path …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

I give a synthetic presentation of loop quantum gravity. I present the aims of the theory and
compare the results obtained with the initial hopes that motivated the early interest in this …

We show that the expected lifetime of white holes formed as remnants of evaporated black
holes is consistent with their production at reheating. We give a simple quantum description …
