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…
Long-wavelength phonon dynamics in incommensurate Bi2Sr2CaCu2O(8+delta) crystals by Brillouin light scattering spectroscopy
Bradley D. E. McNiven, James P. F. LeBlanc, Gordon T. Andrews
Room temperature phonon dynamics in crystals of the high-Tc superconductor Bi2Sr2CaCu2O(8+delta) were probed using Brillouin light scattering spectroscopy. Eight distinct acoustic…
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…
