Persistent spin and mass currents and Aharonov-Casher effect

Abstract

Spin-orbit interaction produces persistent spin and mass currents in a ring via the Aharonov-Casher effect. An experiment in the ${}_{}{}^3{}_{}{}^{}\mathit{A}_1^{}{}_{}{}^{}$ phase in which this effect leads to the excitation of mass and spin supercurrent is proposed.
