Level Statistics and Localization for Two Interacting Particles in a Random Potential
Dietmar Weinmann, Jean-Louis Pichard
We consider two particles with a local interaction in a random potential at a scale (the one particle localization length). A simplified description is provided by a Gaus…
Signatures of electron correlations in the transport properties of quantum dots
Kristian Jauregui, Wolfgang Häusler, Dietmar Weinmann +1
The transition matrix elements between the correlated and electron states of a quantum dot are calculated by numerical diagonalization. They are the central ingredien…
--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…
Nonlinear Transport Properties of Quantum Dots
W. Pfaff, D. Weinmann, W. Haeusler +3
The influence of excited levels on nonlinear transport properties of a quantum dot weakly coupled to leads is studied using a master--equation approach. A charging model for the do…
