摘要：

The possibility of current-carrying ground states due to the Aharonov-Casher effect in mesoscopic and macroscopic systems is discussed. In mesoscopic metal rings, the resulting spontaneous spin currents are dominated by the charge currents due to the Aharonov-Bohm effect. In an annulus-shaped Josephson-junction array, the corresponding vortex current generates a spontaneous voltage across the annulus, which appears to be observable.
