A bstract The isomorphism between the (extended) BMS 4 algebra and the 1+ 2D Carrollian conformal algebra hints towards a co-dimension one formalism of flat holography with the …

A bstract Carrollian Conformal Field Theories (CFTs) have been proposed as co-dimension one holographic duals to asymptotically flat spacetimes as opposed to Celestial CFTs which …
A bstract The Carroll algebra is constructed as the c→ 0 limit of the Poincare algebra and is associated to symmetries on generic null surfaces. In this paper, we begin investigations of …

A bstract We compare and contrast the two approaches of holography in asymptotically flat spacetimes, viz. the co-dimension two Celestial approach based on the Mellin …

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 …

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 …
J Salzer - Journal of High Energy Physics, 2023 - Springer
A bstract Carrollian conformal field theories (carrollian CFTs) are natural field theories on null infinity of an asymptotically flat spacetime or, more generally, geometries with conformal …

In the hydrodynamic regime, field theories typically have their boost symmetry spontaneously broken due to the presence of a thermal rest frame although the associated …
