Quantum Electrodynamics (QED) in one and two spatial dimensions has recently attracted interest in the context of quantum simulations of gauge theories. Currently there is much effort in extending present ideas to higher dimensions and in identifying relevant phenomena accessible with state-of-the art technology.

To this end, we investigate the non-equilibrium dynamics of massive 2+1 dimensional QED for strong electric fields focussing on the broken parity symmetry. In this regime, symmetry violation induces anomalous charge currents which lead to a non-linear electric field rotation. This scenario is analyzed using classical-statistical lattice simulations, which we compare to analytical predictions.
