Fermion propagator for QED3 in the IR domain
C. D. Fosco, A. Lopez
Abstract
We evaluate the fermion propagator in parity-conserving QED3 with N flavours, in the context of an IR domain approximation. This provides results which are non-perturbative in the loopwise expansion sense. We include fermion-loop effects, and show that they are relevant to the chiral symmetry breaking phenomenon, that can be understood in this context.
