Description
We introduce the computational quantum field theory (CQFT) framework for calculating the time-resolved number densities of particle--antiparticle pairs produced by external electromagnetic backgrounds (Schwinger effect). We then extend this framework to curved two-dimensional spacetimes, where the local conformal flatness of the metric enables a simplified treatment of the fermionic dynamics ensuring unitary time evolution with respect to the flat inner product. Finally, we present results for fermion--antifermion pair production induced by spacetime curvature.
