Flat from AdS: in any dimension and for any spin
Xavier Bekaert, Andrea Campoleoni, Simon Pekar +1
The space of solutions to the free equations of motion for massless fields of arbitrary integer spin in Minkowski spacetime is recovered as a smooth limit of the anti-de Sitter sol…

Carrollian-holographic Derivation of Gravitational Flux-Balance Laws
Adrien Fiorucci, Simon Pekar, P. Marios Petropoulos +1
We demonstrate that the BMS evolution equations for the mass and angular momentum aspects in asymptotically flat Einstein gravity follow from local Carroll, Weyl, and diffeomorphis…

Holographic Carrollian Conformal Scalars
Xavier Bekaert, Andrea Campoleoni, Simon Pekar
We provide holographic realisations in Minkowski spacetime of a free conformal Carrollian scalar field living at null infinity. To this end, we first show that the electric and mag…
