Galilean Electrodynamics: Covariant formulation and Lagrangian (2107.08525v1)
Published 18 Jul 2021 in hep-th
Abstract: 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. We write down the Galilean conformal algebra and its representation in this formalism. We also show that the Lagrangian is invariant under the Galilean conformal algebra in d = 4 and calculate the energy-momentum tensor.
