Spatially local energy density of gravitational waves
Antoine Rignon-Bret, Simone Speziale
We propose a new set of BMS charges at null infinity, characterized by a super-translation flux that contains only the `hard' term. This is achieved with a specific corner improvem…

Spinfoams: Foundations
Jonathan Engle, Simone Speziale
Spinfoams provide a framework for the dynamics of loop quantum gravity that is manifestly covariant under the full four-dimensional diffeomorphism symmetry group of general relativ…

General gravitational charges on null hypersurfaces
Gloria Odak, Antoine Rignon-Bret, Simone Speziale
We perform a detailed study of the covariance properties of the symplectic potential of general relativity on a null hypersurface, and of the different polarizations that can be us…
