A bstract We study various aspects of the Carroll limit in which the speed of light is sent to
zero. A large part of this paper is devoted to the quantization of Carroll field theories. We …

Carroll symmetry arises from Poincaré symmetry upon taking the limit of vanishing speed of
light. We determine the constraints on the energy-momentum tensor implied by Carroll …

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 …

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 …

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 …

We discuss three different (conformally) Carrollian geometries and their relation to null
infinity from the unifying perspective of Cartan geometry. Null infinity per se comes with …

We study the small speed of light expansion of general relativity, utilizing the modern
perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll …

Adopting an intrinsic Carrollian viewpoint, we show that the generic Carrollian scalar field
action is a combination of electric and magnetic actions, found in the literature by taking the …

In this paper, we study the Carrollian and Galilean conformal field theories (CCFT and
GCFT) in $ d> 2$ dimensions. We construct the highest weight representations (HWR) of …

We reduce the massless scalar field theory in Minkowski spacetime to future null infinity. We
compute the Poincaré flux operators, which can be generalized and identified as the …
