Quantization of Gravity on Null Hypersurfaces
Luca Ciambelli, Marc S. Klinger
The initial value problem for general relativity on spacelike hypersurfaces is famously captured by the ADM formalism. Less well known is the Cauchy problem for general relativity…
Mapping the Infrared Phase Space of Gravity to Finite Subregions
Luca Ciambelli, Temple He, Marc S. Klinger +1
We construct the phase space for an arbitrary cut of a null hypersurface in Minkowski spacetime and demonstrate that it is symplectomorphic to the infrared phase space of asymptoti…
Asymptotic Limit of Null Hypersurfaces
Luca Ciambelli
We study null hypersurfaces approaching null infinity in asymptotically flat spacetimes within the Bondi-Sachs gauge. The null Raychaudhuri constraint is shown to asymptote to the…
From Asymptotic Symmetries to the Corner Proposal
Luca Ciambelli
These notes are a transcript of lectures given by the author in the XVIII Modave summer school in mathematical physics. The introduction is devoted to a detailed review of the lite…
