Grassmann tensor renormalization group for the massive Schwinger model with a θ term using staggered fermions

Abstract We use the Grassmann tensor renormalization group method to investigate the N f = 2 Schwinger model with the staggered fermions in the presence of a 2π periodic θ term in a broad range of mass. The method allows us to deal with the massive staggered fermions straightforwardly and to study t...
