Carrollian perspective on celestial holography

L Donnay, A Fiorucci, Y Herfray, R Ruzziconi - Physical Review Letters, 2022 - APS
We show that a 3D sourced conformal Carrollian field theory has the right kinematic
properties to holographically describe gravity in 4D asymptotically flat spacetime. The …

Bridging Carrollian and celestial holography

L Donnay, A Fiorucci, Y Herfray, R Ruzziconi - Physical Review D, 2023 - APS
Gravity in 4 d asymptotically flat spacetime constitutes the archetypal example of a
gravitational system with leaky boundary conditions. Pursuing our previous analysis of …

Carrollian amplitudes and celestial symmetries

L Mason, R Ruzziconi, AY Srikant - Journal of High Energy Physics, 2024 - Springer
A bstract Carrollian holography aims to express gravity in four-dimensional asymptotically
flat spacetime in terms of a dual three-dimensional Carrollian CFT living at null infinity …

Conformal Carroll scalars with boosts

S Baiguera, G Oling, W Sybesma, BT Søgaard - SciPost Physics, 2023 - scipost.org
We construct two distinct actions for scalar fields that are invariant under local Carroll boosts
and Weyl transformations. Conformal Carroll field theories were recently argued to be …

The partial Bondi gauge: Further enlarging the asymptotic structure of gravity

M Geiller, C Zwikel - SciPost Physics, 2022 - scipost.org
We present a detailed analysis of gravity in a partial Bondi gauge, where only the three
conditions $ g_ {rr}= 0= g_ {rA} $ are fixed. We relax in particular the so-called determinant …

Flat from anti de Sitter

A bstract Ricci-flat solutions to Einstein's equations in four dimensions are obtained as the
flat limit of Einstein spacetimes with negative cosmological constant. In the limiting process …

Carrollian hydrodynamics from symmetries

L Freidel, P Jai-akson - Classical and Quantum Gravity, 2023 - iopscience.iop.org
In this work, we revisit Carrollian hydrodynamics, a type of non-Lorentzian hydrodynamics
which has recently gained increasing attentions due to its underlying connection with …

Holographic Lorentz and Carroll frames

A Campoleoni, L Ciambelli, A Delfante… - Journal of High Energy …, 2022 - Springer
A bstract Relaxing the Bondi gauge, the solution space of three-dimensional gravity in the

Carrollian amplitudes from holographic correlators

LF Alday, M Nocchi, R Ruzziconi, AY Srikant - arXiv preprint arXiv …, 2024 - arxiv.org
Carrollian amplitudes are flat space amplitudes written in position space at null infinity which
can be re-interpreted as correlators in a putative dual Carrollian CFT. We argue that these …
