One- and two-particle properties of the weakly interacting two-dimensional Hubbard model in proximity to the van Hove singularity

B. D. E. McNiven, Hanna Terletska, G. T. Andrews +1

We study the weak-coupling limit of the Hubbard model on a two-dimensional square lattice using a direct perturbative approach. Aided by symbolic computational tools…

Single particle properties of the 2D Hubbard model for real frequencies at weak coupling: Breakdown of the Dyson series for partial self-energy expansions

Bradley D. E. McNiven, G. Todd Andrews, James P. F. LeBlanc

We generate the perturbative expansion of the single-particle Green's function and related self-energy for a half-filled single-band Hubbard model on a square lattice. We invoke al…
