Zusammenfassung

We study the effect of electronic interactions on the addition spectra and on the energy-level distributions of two-dimensional quantum dots with weak disorder using the self-consistent Hartree- Fock approximation for spinless electrons. We show that the distribution of the conductance peak spacings is Gaussian with large fluctuations that exceed, in agreement with experiments, the mean ...
