Carsten Honerkamp, Daniel Rohe, Sabine Andergassen +1
We propose an interaction flow scheme that sums up the perturbation expansion of many-particle systems by successively increasing the interaction strength. It combines the unbiased…

Functional renormalization group for Luttinger liquids with impurities
S. Andergassen, T. Enss, V. Meden +3
We improve the recently developed functional renormalization group (fRG) for impurities and boundaries in Luttinger liquids by including renormalization of the two-particle interac…
