The chiral limit of non-compact QED(3)

Abstract

Non-compact QED(3) with four-component fermion flavor content larger than or equal to two is studied numerically near the chiral limit to understand its chiral symmetry breaking features. We monitor discretization and finite size effects on the chiral condensate by simulating the model at different values of the gauge coupling on lattices ranging in size from 10^3 to 50^3. Our upper bound for the dimensionless condensate beta^2<psibarpsi> in the N_f=2 case is 5x10^{-5}.
