Notes: Abstract A Green's function decoupling method is shown to yield quasiparticle bands for the 2D Hubbard model in excellent agreement with the Monte Carlo results of Bulut et al. The same approach gives d-wave superconductivity with Tc in the range 10–100K for a band-width of 4eV, on-site interaction U = 2eV and the Fermi level close to a van Hove singularity.
