Spin and interaction effects in quantum dots: a Hartree-Fock-Koopmans approach
arXiv:cond-mat/0202453 · doi:10.1103/PhysRevB.66.245313
Abstract
We use a Hartree-Fock-Koopmans approach to study spin and interaction effects in a diffusive or chaotic quantum dot. In particular, we derive the statistics of the spacings between successive Coulomb-blockade peaks. We include fluctuations of the matrix elements of the two-body screened interaction, surface-charge potential, and confining potential to leading order in the inverse Thouless conductance. The calculated peak-spacing distribution is compared with experimental results.
