摘要：

We have calculated persistent currents in a special type of closed geometry where we can excite evanescent modes throughout the circumference of the current carrying ring. The parity effect is totally absent in the persistent current, due to evanescent modes. We can also completely destroy the parity effect in the case of propagating modes by tuning some length scales. Finally, we briefly comment on impurities in the form of geometric irregularities and their consequences. © 1995 The American Physical Society.
