Interrelation between antiferromagnetic and superconducting gaps in high-Tc materials
E. Arrigoni, M. G. Zacher, T. Eckl +1
We propose a phenomenological model, comprising a microscopic \sof model plus the on-site Hubbard interaction (``projected \sof model'') to understand the interrelation between…

Screening of long-range Coulomb interactions in the quasi two-dimensional extended Hubbard model: A combined quantum Monte Carlo and Feynman diagram study
H. -B. Schüttler, C. Gröber, H. G. Evertz +1
By combining fermion Quantum Monte Carlo (QMC) simulations with diagrammatic theory, we have calculated the dielectric screening and the screened potential, in a quasi 2D Hubbard m…
