V. Azcoiti et al., FERMIONIC EFFECTIVE ACTION AND THE PHASE-STRUCTURE OF NONCOMPACT QUANTUM ELECTRODYNAMICS IN 2+1 DIMENSIONS, Physics letters. Section B, 313(1-2), 1993, pp. 180-186
We study the phase diagram of noncompact QED3 using the microcanonical
fermionic average method described elsewhere. We present evidence for
a continuous phase transition line in the (beta, N) plane, extending
down to an arbitrarily small flavour number N.
