In approximate dynamical equations, inhomogenous classical (mean) gauge and Higgs elds are coupled to
quantized fermions. The equations are solved numerically on a spacetime lattice. The fermions appear to equili
brate according to the FermiDirac distribution with timedependent temperature and chemical potential.
1. The realtime path integral for quantum
elds is very diĘcult to evaluate numerically and
approximations need to be made before giving
