Abstract

We study the parity (electron number) dependence of persistent currents due to the Aharonov-Casher effect for a system of noninteracting many electrons in a one-dimensional mesoscopic ring in the presence of a cylindrically symmetric electric field. The persistent charge and spin currents, and the magnetization for the ground-state of the system are calculated. We find the period and amplitude halving of the persistent spin current due to the Aharonov-Casher effect, which is dual to that of the persistent charge current due to the Aharonov-Bohm effect.
