大型抗磁持续电流

Large diamagnetic persistent currents

Sheelan Sengupta Chowdhury, P. Singha Deo, Ashim Kumar Roy, M. Manninen

摘要:

在多通道环中,倏逝模将总是与传播模共存。倏逝模可以携带非常大的抗磁持续电流,该电流可以随能量振荡并且对杂质散射非常敏感。这为实验中观察到的大的抗磁持续电流提供了一个自然的解释。

英文摘要:

In multichannel rings, evanescent modes will always co-exist with propagating modes. The evanescent modes can carry a very large diamagnetic persistent current that can oscillate with energy and are very sensitive to impurity scattering. This provides a natural explanation for the large diamagnetic persistent currents observed in experiments.
