Query: Non-compact QED_3 with N_f >=2   Non-compact three-dimensional QED is studied by computer simulations to
understand its chiral symmetry breaking features for N_f>=2, on lattice volumes
up to 50^3 and bare masses as low as ma=0.0000625. We compute the chiral
condensate, scalar and pseudoscalar susceptibilities, and the masses of scalar
and pseudoscalar mesons. Finite volume effects and discretisation artifacts are
carefully monitored. Our results reveal no decisive signal for chiral symmetry
breaking for any N_f>=2. For N_f=2 the dimensionless condensate can be bounded
by beta^2<psibarpsi> <= 5x10^-5. We also present an exploratory study of the
fractionally-charged Polyakov line.
