Quasi-particle functional renormalisation group calculations in the two-dimensional t-t'-Hubbard model
We extend and apply a recently introduced quasi-particle functional renormalisation group scheme to the two-dimensional Hubbard model with next-nearest-neighbour hopping and away from half filling. We confirm the generation of superconducting correlations in some regions of the phase diagram, but al...
