Effects of correlations and disorder on the persistent current in mesoscopic metallic rings

We study the influence of e-e interactions on persistent currents in mesoscopic metallic rings by means of a Hamiltonian which incorporates diagonal disorder (substitional impurities) and where correlations are included up to 2nd order perturbation theory. The results are depending on the degree of...
