Two interacting particles in a random potential (1105.2637v1)
Published 13 May 2011 in cond-mat.dis-nn, nlin.CD, and quant-ph
Abstract: We study the scaling of the localization length of two interacting particles in a one-dimensional random lattice with the single particle localization length. We obtain several regimes, among them one interesting weak Fock space disorder regime. In this regime we derive a weak logarithmic scaling law. Numerical data support the absence of any strong enhancement of the two particle localization length.
