Galilean Gauge Theories from Null Reductions
Arjun Bagchi, Rudranil Basu, Minhajul Islam +2
The procedure of null reduction provides a concrete way of constructing field theories with Galilean invariance. We use this to examine Galilean gauge theories, viz. Galilean elect…
Galilean Electrodynamics: Covariant formulation and Lagrangian
Aditya Mehra, Yaman Sanghavi
In this paper, we construct a single Lagrangian for both limits of Galilean electrodynamics. The framework relies on a covariant formalism used in describing Newton-Cartan geometry…
Field Theories on Null Manifolds
Arjun Bagchi, Rudranil Basu, Aditya Mehra +1
We argue that generic field theories defined on null manifolds should have an emergent BMS or conformal Carrollian structure. We then focus on a simple interacting conformal Carrol…
Field Theories with Conformal Carrollian Symmetry
Arjun Bagchi, Aditya Mehra, Poulami Nandi
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 spacetime. The…
