Competing electronic instabilities of extended Hubbard models on the honeycomb lattice: A functional Renormalization Group calculation with high wavevector resolution
D. Sánchez de la Peña, J. Lichtenstein, C. Honerkamp
We investigate the quantum many-body instabilities for electrons on the honeycomb lattice at half-filling with extended interactions, motivated by a description of graphene and rel…
Tight-binding Rashba model and statistical field theory
G. A. H. Schober, K. -U. Giering, M. M. Scherer +2
This document contains information supplementary to the article [1], but it is self-contained and can be read independently as a pedagogical review. In the first part, we explain o…
Functional renormalization group study of an eight-band model for the iron arsenides
J. Lichtenstein, S. A. Maier, C. Honerkamp +4
We investigate the superconducting pairing instabilities of eight-band models for the iron arsenides. Using a functional renormalization group treatment, we determine how the criti…
Electron-doping versus hole-doping in the 2D t-t' Hubbard model
Carsten Honerkamp
We compare the one-loop renormalization group flow to strong coupling of the electronic interactions in the two-dimensional t-t'-Hubbard model with t'=-0.3t for band fillings small…
