Persistent currents in diffusive metallic cavities: Large values and anomalous scaling with disorder

Mostrar todas las versiones(4)

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...
