Abstract

We have shown that the DMRG allows the study of interacting, disordered one-dimensional Fermi systems, but: care has to be taken. The scaling arguments provide a test for a DMRG implementation. In addition we have shown that the results of Giamarchi and Schulz can be obtained with Kane and Fisher scaling, and that the scaling results are valid beyond the perturbative regime. In the regime of strong disorder we find a “delocalization of reorganization” effect for repulsive interaction which has a strong sample dependence.
