This study reviews the history of Newton–Cartan (NC) gravity with an emphasis on recent developments, including the covariant, off-shell large speed of light expansion of general …
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 …
A bstract We initiate a study of gravity focusing on generic null hypersurfaces, non- perturbatively in the Newton coupling. We present an off-shell account of the extended …

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 …
We review both the kinematics and dynamics of non-lorentzian theories and their associated geometries. First, we introduce non-lorentzian kinematical spacetimes and their symmetry …

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 Bagchi, P Dhivakar, S Dutta - Journal of High Energy Physics, 2024 - Springer
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 …

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 …
