Physical Review B, 93(20), 205445. doi.org/10.1103/PhysRevB.93.2054452469-99502469-9969 (eISSN)https://hdl.handle.net/20.500.11815/851We 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.1-6eninfo:eu-repo/semantics/openAccessQuantum wellsTubesNanowiresHeterostructuresNanóvírarRaffræðiHálfleiðararinfo:eu-repo/semantics/articlePhysical Review10.1103/PhysRevB.93.205445
