dc.description.abstract |
We analyze theoretically electronic transport through a core-shell nanowire in the presence of a transversal
magnetic field. We calculate the conductance for a variable coupling between the nanowire and the attached
leads and show how the snaking states, which are low-energy states localized along the lines of the vanishing
radial component of the magnetic field, manifest their existence. In the strong-coupling regime they induce flux
periodic, Aharonov-Bohm-like, conductance oscillations, which, by decreasing the coupling to the leads, evolve
into well-resolved peaks. The flux periodic oscillations arise due to interference of the snaking states, which is a
consequence of backscattering at either the contacts with leads or magnetic or potential barriers in the wire. |

Authors can pay an article-processing charge (APC) to make accepted manuscripts immediately accessible on publication under a CC-BY (4.0 International) license. In keeping with APS's community orientation, this is the most permissive license available at this time and permits anyone to copy, distribute, transmit, and adapt the work with proper attribution. APCs cover publishing costs and decrease the need for subscription revenue, helping to keep subscription prices low (current APS APCs).
APS authors are free to post the final published version of their articles on their laboratory and institutional web sites. |
