Recent attempts at the construction of holography for asymptotically flat spacetime have
taken two different routes. Celestial holography, involving a two dimensional (2D) conformal …

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 Assuming the existence of a field theory in D dimensions dual to (D+ 1)-
dimensional flat space, governed by the asymptotic symmetries of flat space, we make some …

Carrollian field theories at the classical level possess an infinite number of space-time
symmetries, namely the supertranslations. In this article, we inquire whether these …

A bstract Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll
symmetries, are intrinsically associated to null manifolds and in two dimensions can be …

We probe the contraction from 2 d relativistic CFTs to theories with Bondi-Metzner-Sachs
(BMS) symmetries, or equivalently conformal Carroll symmetries, using diagnostics of …

A bstract Conformal Carrollian groups are known to be isomorphic to Bondi-Metzner-Sachs
(BMS) groups that arise as the asymptotic symmetries at the null boundary of Minkowski …

We present the analytical calculation of entanglement entropy for a class of two-dimensional
field theories governed by the symmetries of the Galilean conformal algebra, thus providing …

A bstract Conformal Carroll symmetry generically arises on null manifolds and is important
for holography of asymptotically flat spacetimes, generic black hole horizons and …

A bstract The conformal symmetry algebra in 2D (Diff (S 1)⊕ Diff (S 1)) is shown to be
related to its ultra/non-relativistic version (BMS 3≈ GCA 2) through a nonlinear map of the …
