【 摘 要 】
We study the spin-dependent geometric phase effect in mesoscopic rings of charge-density-wave (CDW) materials. When electron spin is explicitly taken into account, we show that the spin-dependent Aharonov-Casher phase can have pronounced frustration effects on such CDW materials with appropriate electron filling. We show that this frustration has observable consequences for transport experiments. We identify a phase transition from a Peierls insulator to metal, which is induced by spin-dependent phase interference effects. Mesoscopic CDW materials and spin-dependent geometric phase effects, and their interplay, are becoming attractive opportunities for exploitation with the rapid development of modern fabrication technology.
