Analytical study of Lattice U(1) and U(1)-Higgs Models at Finite Temperature With Symanzik Action

  • The lattice U(1) and U(1) -Higgs models with Symanzik action are analytically studied at finite temperature using variational cumulant expansion (VCE). The Polyakov lines and the critical index β are calculated. The results show that VCE of system with Symanzik action converges more rapidly than that of Wilson action.

Abstract: The lattice U(1) and U(1) -Higgs models with Symanzik action are analytically studied at finite temperature using variational cumulant expansion (VCE). The Polyakov lines and the critical index β are calculated. The results show that VCE of system with Symanzik action converges more rapidly than that of Wilson action.
