Effective Model Formulation for Two Interacting Electrons in a Disordered Metal
Klaus Frahm, Axel M"uller--Groeling, Jean-Louis Pichard
We derive an analytical theory for two interacting electrons in a --dimensional random potential. Our treatment is based on an effective random matrix Hamiltonian. After mapping…
Analytical Results for Random Band Matrices with Preferential Basis
Klaus Frahm, Axel Müller--Groeling
Using the supersymmetry method we analytically calculate the local density of states, the localiztion length, the generalized inverse participation ratios, and the distribution fun…
--Oscillations for Correlated Electron Pairs in Disordered Mesoscopic Rings
D. Weinmann, A. Mueller-Groeling, J. -L. Pichard +1
The full spectrum of two interacting electrons in a disordered mesoscopic one--dimensional ring threaded by a magnetic flux is calculated numerically. For ring sizes far exceeding…
Scaling in Interaction-Assisted Coherent Transport
K. Frahm, A. Mueller-Groeling, J. -L. Pichard +1
The pair localization length of two interacting electrons in one--dimensional disordered systems is studied numerically. Using two direct approaches, we find $L_2 \propto L_1…
