Abstract: Abstract We derive a general formula of the tensor network representation for d-dimensional lattice fermions with ultra-local interactions, including Wilson fermions, staggered fermions, and domain-wall fermions. The Grassmann tensor is concretely defined with auxiliary Grassmann… read more here.

Abstract: We use the Grassmann tensor renormalization group method to investigate the Nf = 2 Schwinger model with the staggered fermions in the presence of a 2π periodic θ term in a broad range of mass.… read more here.
