Orbital currents and charge density waves in a generalized Hubbard ladder
J. O. Fjaerestad, J. B. Marston, U. Schollwoeck
We study a generalized Hubbard model on the two-leg ladder at zero temperature, focusing on a parameter region with staggered flux (SF)/d-density wave (DDW) order. To guide our num…

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…
