Abstract
We make an analysis of the two-dimensional U(1) lattice gauge theory with a term by using the tensor renormalization group. Our numerical result for the free energy shows good consistency with the exact one at finite coupling constant. The topological charge density generates a finite gap at toward the thermodynamic limit. In addition finite size scaling analysis of the topological susceptibility up to allows us to determine the phase transition at is the first order.
