Effect of a nonuniform magnetic field on a two-dimensional electron gas in the ballistic regime
Abstract
The single-particle electronic structure of a two-dimensional electron gas in a nonuniform magnetic field B consists of states that propagate perpendicularly to the field gradient \ensuremath{\nabla}B and have a remarkable time-reversal asymmetry. In one of the allowed directions the propagation has free-electron character and is confined to a narrow one-dimensional channel localized about the region where \ensuremath{\Vert}B\ensuremath{\Vert} is minimum. In the opposite direction, the Landau states propagate throughout the rest of the sample with a velocity proportional to \ensuremath{\Vert}\ensuremath{\nabla}B${\mathrm{\ensuremath{\Vert}}}^{1/2}$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
