Studies on Carrollian quantum field theories
Abstract
Abstract We examine the quantum field description of massive Carrollian field theories, emphasizing the critical role of gauge fixing within the Carrollian sector. We illustrate this importance using scalar Carrollian electrodynamics (sCEDs) as a primary example. We also present the quantum field description for complex Carrollian scalar fields, Carrollian fermions, and CEDs. We highlight the challenges in sCEDs, where the renormalized mass appears gauge-dependent, and clarify this discrepancy by carefully constructing completely gauge-fixed propagators. We discuss how certain abelian Carrollian field theories do not admit any loop corrections and are trivial in that sense.
