Torsion-induced persistent current in a twisted quantum ring

Mesoscale and Nanoscale Physics 2015-05-13 v2 Other Condensed Matter

Abstract

We describe the effects of geometric torsion on the coherent motion of electrons along a thin twisted quantum ring. The geometric torsion inherent in the quantum ring triggers a quantum phase shift in the electrons' eigenstates, thereby resulting in a torsion-induced persistent current that flows along the twisted quantum ring. The physical conditions required for detecting the current flow are discussed.
