Renormalization group study of Luttinger liquids with boundaries — •Stephan Grap and Volker Meden — Inst. Theo. Physik A RWTH Aachen

We use Wilsons weak coupling ``momentum'' shell renormalization group method to show that two-particle interaction terms commonly neglected in bosonization of one-dimensional correlated electron systems with open boundaries are indeed irrelevant in the renormalization group sense. Our study provides a more solid ground for many investigations of Luttinger liquids with open boundaries.
