Non-trivial Fock vacuum of the light-front Schwinger model

A Fock representation for the physical vacuum based on the dynamical zero mode of the gauge field is suggested for the Schwinger model quantized on the light front. The θ-vacuum in terms of a gauge invariant superposition of zero-mode coherent states is shown to reproduce the vacuum-angle dependence of the fermion condensate within the bosonized formulation of the model.
