关于Aharanov-Bohm效应和几何相位的注记

Remarks on Aharanov-Bohm effect and geometric phase

S C Tiwari

摘要:

近年来,光学中几何相位的物理机制已根据1992年提出的角动量完整论得到了阐明。Aharonov和Kaufherr(PRL,92,070404,2004)重新讨论了Aharonov-Bohm效应,并提出了一个保守的、规范不变的量的非定域交换,该量改变了负责AB相移的粒子的模动量。我们认为,GP提出的净角动量位移可能类似于AB效应的模动量位移。在单个光子或电子水平上,这种非平凡的几何效应似乎暗示着一种新的物理学。

英文摘要:

Recently the physical mechanism for geometric phase in optics has been elucidated in terms of the angular momentum holonomy proposed in 1992. Aharonov and Kaufherr (PRL, 92, 070404, 2004) revisit the Aharonov-Bohm effect, and propose non-local exchange of a conserved, gauge invariant quantity that changes the modular momentum of the particle that is responsible for the AB phase shift. We suggest that the net angular momentum shifts proposed for GP may be analogous to the shift in the modulus momentum for the AB effect. At a single photon or electron level such non-trivial, geometric effects seem to hint at a new physics.
