Screened-interaction expansion for the Hubbard model and determination of the quantum Monte Carlo Fermi surface
G. Esirgen, H. -B. Schuttler, C. Grober +1
We develop a systematic self-consistent perturbative expansion for the self energy of Hubbard-like models. The interaction lines in the Feynman diagrams are dynamically screened by…

d-Wave Pairing in the Presence of Long-Range Coulomb Interactions
G. Esirgen, H. -B. Schüttler, N. E. Bickers
The one-band extended Hubbard model in two dimensions near band-filling 1/2 is solved in the fluctuation exchange approximation, including the long-range (1/r) part of the Coulomb…
