Description
Motivated by recent applications of Carroll symmetry, various Carroll-invariant field theories have been constructed and studied. Two distinct Carrollian theories, commonly referred to as magnetic and electric, can be obtained. In this talk, I will present the Carroll limits of relativistic spin-1/2 Dirac fermions in arbitrary spacetime dimensions. I will explain the subtlety that arise with fermions due to the first order nature of their Lagrangians, and how one can nevertheless obtain two different Carrollian limits. I will also briefly discuss possible generalisations to higher-spin Carroll fermionic fields.
