Interacting Galilean and Finite-Energy Carroll Fermions
Pulastya Parekh, Aditya Sharma, Mauricio Valenzuela
We present a unified derivation of the Galilean and Carrollian limits of the massive Dirac action based on a similarity transformation depending on the mass and the speed of light.…

Carroll fermions from null reduction: A case of good and bad fermions
Sucheta Majumdar, Aditya Sharma, Sourav Singha
We derive Carrollian fermionic actions using the null reduction method from Bargmann spacetimes. In the Lorentzian light-cone formulation, the Dirac spinor naturally decomposes int…

Studies on Carrollian Quantum Field Theories
Aditya Sharma
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 import…
