Carroll-Weyl symmetries in flat holography
Arnaud Delfante, Chrysoula Markou
The degenerate geometry of a null boundary admits an enlarged local conformal freedom: in two dimensions, a Carrollian coframe allows two independent Weyl rescalings, one modulatin…
Asymptotically-FLRW spacetimes
Andrea Campoleoni, Arnaud Delfante, Marc Geiller +1
We introduce three-dimensional asymptotically-FLRW spacetimes as a simplified setting in which to study asymptotic symmetries and radiation in cosmology. Their asymptotic symmetry…
Holographic realization of higher-spin Carrollian free fields
Ethan D'Arcy, Arnaud Delfante, Stefan Fredenhagen
We provide a holographic bulk realization of Carrollian free-field structures arising in three-dimensional asymptotically flat (higher-spin) gravity. We construct a class of bounda…
