Abstract:

The effect of disorder on confined metallic cavities with an Aharonov-Bohm flux line is addressed. We find that, even deep in the diffusive regime, large values of persistent currents may arise for a wide variety of geometries. We present numerical results supporting an anomalous scaling law of the average typical current 〈I typ〉 with the strength of disorder w, 〈I typ〉∼w -γ with γ<2. This is contrasted with previously reported results obtained for cylindrical samples where a scaling 〈I typ〉∼ -2 has been found. Possible links to, up to date, unexplained experimental data are finally discussed.
