On Carrollian and Celestial Correlators in General Dimensions
Harshal Kulkarni, Romain Ruzziconi, Akshay Yelleshpur Srikant
Carrollian holography is a framework for flat space holography, suggesting that gravity in asymptotically flat spacetime in dimensions is dual to a conformal Carrollian field t…
Towards a Flat Space Carrollian Hologram from AdS/CFT
Arthur Lipstein, Romain Ruzziconi, Akshay Yelleshpur Srikant
Finding a concrete example holography in four dimensional asymptotically flat space is an important open problem. A natural strategy is to take the flat space limit of the celebrat…
Celestial charges from a twistor action
Adam Kmec, Lionel Mason, Romain Ruzziconi +1
The celestial symmetries in asymptotically flat spacetimes have a natural geometric interpretation on twistor space in terms of Poisson diffeomorphisms. Using this…
Landau Singularities of the 7-Point Ziggurat II
Luke Lippstreu, Marcus Spradlin, Akshay Yelleshpur Srikant +1
We solve the Landau equations to find the singularities of nine three-loop 7-point graphs that arise as relaxations of the graph studied in arXiv:2211.16425. Along the way we estab…
