Quantum Null Geometry and Gravity
Luca Ciambelli, Laurent Freidel, Robert G. Leigh
In this work, we demonstrate that quantizing gravity on a null hypersurface leads to the emergence of a CFT associated with each null ray. This result stems from the ultralocal nat…

On the Definition of the Spin Charge in Asymptotically-Flat Spacetimes
Laurent Freidel, Seyed Faroogh Moosavian, Daniele Pranzetti
We propose a solution to a classic problem in gravitational physics consisting of defining the spin associated with asymptotically-flat spacetimes. We advocate that the correct asy…
