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.

Abstract: We explore the phase structure of a four dimensional SO(4) invariant lattice Higgs-Yukawa model comprising four reduced staggered fermions interacting with a real scalar field. The fermions belong to the fundamental representation of the symmetry… read more here.

Abstract: The geometry of center vortices is studied in the novel lattice-artefact phase that appears with staggered fermions to elucidate any insight provided by the center-vortex degrees of freedom. For various numbers of fermion flavors, the… read more here.
