Abstract / Description:Two electrons move in a quasi one-dimensional wire under the influence of a short-range interaction. We restrict Hilbert space to those states where the two electrons are close to each other. Using supersymmetry, we present a complete analytical solution to this problem. The two-body interaction affects the density of states and, thereby, the localization length. We derive a criterion for the onset of changes of the localization length due to the two-body interaction.
