Abstract
The influence of zero-momentum gauge modes on physical observables is inves tigated for compact lattice QED with dynamical and quenched Wilson fermions . Within the Coulomb phase, zero-momentum modes are shown to hide the criti cal behavior of gauge invariant fermion observables near the chiral limit. Methods for eliminating zero-momentum modes are discussed.
