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…

Carroll theories from Lorentzian light-cone theories
Sucheta Majumdar
We derive Carrollian field theories via null reduction from Lorentzian light-cone actions in Minkowski spacetime. By suitably deforming the light-cone action, we reduce the Poincar…

On the Carrollian Nature of the Light Front
Sucheta Majumdar
Motivated by recent advances in non-Lorentzian physics, we revisit the light-cone formulation of quantum field theories. We discuss some interesting subalgebras within the light-co…
