Gravitational null rays: Covariant Quantization and the Dressing Time
Laurent Freidel, Josh Kirklin
We quantize the degrees of freedom on a gravitational null ray segment in a fully gauge-invariant manner by using the dressing time as a quantum reference frame (QRF). Our work goe…
Celestial 1-form symmetries
Laurent Freidel, Atul Sharma
The -algebra originally arose as a chiral algebra of asymptotic symmetries of Yang-Mills theory. We show that in the self-dual sector of Yang-Mills, the -algebra gets upgrade…
Localization and anomalous reference frames in gravity
Laurent Freidel, Josh Kirklin
In this work, we study the classical phase space for the gravitational degrees of freedom along a null ray. We construct gauge-invariant observables localized on a null ray segment…
Non-Perturbative -matrix Renormalization
Laurent Freidel, José Padua-Argüelles, Susanne Schander +1
We propose a renormalization group flow equation for a functional that generates -matrix elements and which captures similarities to the well-known Wetterich and Polchinski equa…
Asymptotic Higher Spin Symmetries IV: Einstein-Yang-Mills Theory
Nicolas Cresto, Laurent Freidel
We generalize the analysis of the asymptotic higher spin symmetries developed in the first three parts of this series by considering the minimal coupling of Einstein Gravity and Ya…
Asymptotic Higher Spin Symmetries II: Noether Realization in Gravity
Nicolas Cresto, Laurent Freidel
In this paper we construct a non-perturbative action of the higher spin symmetry algebra on the gravitational phase space. We introduce a symmetry algebroid which all…
Asymptotic Higher Spin Symmetries I: Covariant Wedge Algebra in Gravity
Nicolas Cresto, Laurent Freidel
In this paper, we study gravitational symmetry algebras that live on 2-dimensional cuts of asymptotic infinity. We define a notion of wedge algebra which depen…
Geometry of Carrollian Stretched Horizons
Laurent Freidel, Puttarak Jai-akson
In this paper, we present a comprehensive toolbox for studying Carrollian stretched horizons, encompassing their geometry, dynamics, symplectic geometry, symmetries, and correspond…
Renormalization of conformal infinity as a stretched horizon
Laurent Freidel, Aldo Riello
In this paper, we provide a comprehensive study of asymptotically flat spacetime in even dimensions . We analyze the most general boundary condition and asymptotic symmetr…
Carrollian representation from twistor space
Laura Donnay, Laurent Freidel, Yannick Herfray
We construct an explicit realization of the action of the loop algebra on fields at null infinity. This action is directly derived by Penrose transform of the geome…
