摘要：
We study the phase structure of the U(1) lattice scalar-fermion theory with Yukawa interaction in the mean field approximation. Four phases are found: a spontaneously broken phase (〈φ〉≠ 0), a symmetric phase (〈φ〉 = 0) with massless fermions, a symmetric phase without them and an antiferromagnetically ordered phase. The phase transition lines are in a good agreement with recent Monte Carlo simulations. © 1990.
