MICROSCOPIC FRACTIONAL PERSISTENT CURRENT OSCILLATIONS IN A METALLIC RING WITH THE ANDERSON IMPURITY
Keyword(s):
Microscopic spin and charge persistent currents in a metallic ring with the Anderson magnetic impurity are studied. It is shown that the impurity changes caused by the external magnetic and electric fluxes, the Aharonov-Bohm and Aharonov-Casher oscillations (magnitudes and periods), contrast with the normal metallic case. Spin-charge separation is the reason for the fractional Φ0/N (N is the number of electrons) period of the Aharonov-Bohm oscillations and F0/(N−2M) (M is the number of paired electrons) period of the Aharonov-Casher oscillations.
