Flux-Free Aharonov-Bohm Effect in a Helical Circuit | | Hisao Taira
; Hiroyuki Shima
; | | Date: |
1 Feb 2010 | | Abstract: | A novel conductance oscillation in a twisted quantum ring composed of a
helical atomic configuration is theoretically predicted. The internal torsion
of the ring induces a quantum phase shift in the wavefunction that describes
the electron’s motion along the ring. The resulting conductance oscillation is
free from magnetic flux penetrating inside the ring, which is in complete
contrast with the ordinary Aharonov-Bohm effect observed in untwisted
nanorings. | | Source: | arXiv, 1002.0079 | | Services: | Forum | Review | PDF | Favorites | |
