Theory of Aharonov-Bohm Effect in Small Normal Metals

抄録

A theory of the conductance oscillation with flux period hc⁄e in a small normal metal ring with long leads is developed. We find that (i) the oscillation is strongly affected by leads, and (ii) the magnitude of the conductance fluctuations of the ring depends crucially on size and material of the ring and leads. The temperature dependence of the oscillation is consistent with experiments.
