Abstract

We report on the unusual nature of the $\ensuremath{\nu}=0$ state in the integer quantum Hall effect (QHE) in graphene and show that electron transport in this regime is dominated by counterpropagating edge states. Such states, intrinsic to massless Dirac quasiparticles, manifest themselves in a large longitudinal resistivity ${\ensuremath{\rho}}_{xx}\ensuremath{\gtrsim}h/{e}^{2}$, in striking contrast to ${\ensuremath{\rho}}_{xx}$ behavior in the standard QHE. The $\ensuremath{\nu}=0$ state in graphene is also predicted to exhibit pronounced fluctuations in ${\ensuremath{\rho}}_{xy}$ and ${\ensuremath{\rho}}_{xx}$ and a smeared zero Hall plateau in ${\ensuremath{\sigma}}_{xy}$, in agreement with experiment. The existence of gapless edge states puts stringent constraints on possible theoretical models of the $\ensuremath{\nu}=0$ state.

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.
