Abstract：
Using variational cumnulant expansion we study the lattice U(1) gauge-Higgs models with fixed modulus To determine the variational parameters, we combine main-value method and accumulated point method. The phase diagrams obtained are consistent with Monte Carlo results. We also calculate Polyakov line 〈L〉 with N_τ=1 in finite temperature.
