THE SPONTANEOUS AHARONOV-CASHER EFFECT ASSOCIATED WITH PARTIALLY SPIN-POLARIZED STATES IN ONE-DIMENSIONAL MESOSCOPIC RINGS

The spontaneous Aharonov-Casher (AC) effect associated with partially spin-polarized states in one-dimensional mesoscopic rings is investiga ted for the first time. The results obtained seem to be novel and inte resting. Particularly, for an even number of electrons, the spontaneou sly introduced AC flux does not depend on the polarization parameter N (p); while for an odd number of electrons, it increases with a specifi c set of N(p) and decreases with the other set. Moreover, the polariza tion magnetic field is calculated analytically.
