Single-boson exchange functional renormalization group application to the two-dimensional Hubbard model at weak coupling
ABSTRACT: We illustrate the algorithmic advantages of the recently introduced single-boson exchange (SBE) formulation for the one-loop functional renormalization group (fRG), by applying it to the two-dimensional Hubbard model on a square lattice. We present a detailed analysis of the fermion-boson...
