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…
