An outstanding open issue in our quest for physics beyond Einstein is the unification of
general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading …

Recent advances in classical machine learning have shown that creating models with
inductive biases encoding the symmetries of a problem can greatly improve performance …

A bstract This is the first paper in a series devoted to understanding the classical and
quantum nature of edge modes and symmetries in gravitational systems. The goal of this …

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 …

A bstract In this second paper of the series we continue to spell out a new program for

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 …

Varying the gravitational Lagrangian produces a boundary contribution that has various
physical applications. It determines the right boundary terms to be added to the action once …
