Anomalous phase shift in a twisted quantum loop
Hisao Taira, Hiroyuki Shima
Coherent motion of electrons in a twisted quantum ring is considered to explore the effect of torsion inherent to the ring. Internal torsion of the ring composed of helical atomic…
Flux-free conductance modulation in a helical Aharonov-Bohm interferometer
Hisao Taira, Hiroyuki Shima
A novel conductance oscillation in a twisted quantum ring composed of a helical atomic configuration is theoretically predicted. Internal torsion of the ring is found to cause a qu…
Torsion-induced persistent current in a twisted quantum ring
Hisao Taira, Hiroyuki Shima
We describe the effects of geometric torsion on the coherent motion of electrons along a thin twisted quantum ring. The geometric torsion inherent in the quantum ring triggers a qu…
Curvature effects on surface electron states in ballistic nanostructures
Hisao Taira, Hiroyuki Shima
The curvature effect on the electronic states of a deformed cylindrical conducting surface of variable diameter is theoretically investigated. The quantum confinement of electrons…
