The Continuum Limit Analysis of Causal Fermion Systems for Curved Spacetimes
Causal fermion systems are constructed for globally hyperbolic spacetimes such that their continuum limit satisfies the Euler-Lagrange equations of the causal action principle if and only if the coupled Einstein-Dirac...

Construction of Currents in Causal Fermion Systems
A probing construction on the linearized causal action recovers Maxwell's equations at rank one, with coupling independent of the regularization length.
