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…

Boundary freedom in higher spin gravity
Arnaud Delfante
We investigate new boundary conditions in three-dimensional asymptotically Anti-de Sitter gravity coupled to higher-spin fields, allowing for arbitrary boundary degrees of freedom.…

Finite actions and asymptotic charges at null infinity for any spin
Andrea Campoleoni, Arnaud Delfante, Dario Francia +1
We identify boundary terms renormalizing the free on-shell actions for massless fields of arbitrary spin, including electromagnetism and linearized gravity, with boundary condition…
