We consider the dynamics of the 1 + 1 dimensional abelian Higgs model with axially coupled
fermions, in the large Nf limit, on a lattice in space and real-time. We allow for inhomogeneous
classical Bose elds. In order to deal with the lattice doublers, we use Wilson's lattice fermions.
The lattice formulation leads to a stable integration algorithm. We illustrate the implementation
with numerical results.
I. INTRODUCTION
Real-time dynamics of quantum elds plays an impor-
tant role in the early universe, in heavy ion collisions
and in condensed matter. For example, a detailed un-
