| dc.description.abstract | The singular value decomposition technique is used to reconstruct the electronic spectral weight function for a half-filled Hubbard model with on-site repulsion U = 4t from quantum Monte Carlo data. A two-band structure for the single-particle excitation spectrum is found to persist as the lattice size exceeds the spin-spin correlation length. The observed bands are flat in the vicinity of the (0, π), (π, 0) points in the Brillouin zone, in accordance with experimental data for high-temperature superconducting compounds. | |
