The quantum Hall conductance of a disordered two-dimensional gas of non-interacting electrons is re-examined for its integrity against disorder in the limit of no mixing between different Landau levels. May 2013; Nature 497:598; DOI: 10.1038/nature12186. Export citation and abstract In a previous paper we showed that a substantial DOS between LL's can be obtained using nonperturba- tive methods for electrons interacting with disorder hav- : Condens.

We show that the Fermi arcs can give rise to a distinctive 3D quantum Hall effect in topological semimetals. The longitudinal conductance minimums of the system corresponding to the Hall plateaus become narrower and thinner with disorder, and those of the ABC-stacked TLG are comparatively more stable than those of the ABA structure. 3. This … The model also has bulk chiral fermions at certain special points in the parameter space.

Phys. A topological invariant Chern number description provides a consistent understanding of … There are no localized states. The quantum Hall effect in graphene p − n junctions is studied numerically with emphasis on the effect of disorder at the interface of two adjacent regions. Conductance plateaus are found to be attached to the intensity of the disorder and are accompanied by universal conductance fluctuations in the bipolar regime, which is in good agreement with theoretical predictions of the random matrix … H Y Tian 1,2, R Ma 3, K S Chan 4,5 and J Wang 1. Integer Quantum Hall effect • basics • theories for the quantization • disorder in QHS • Berry phase in QHS • topology in QHS • effect of lattice • effect of spin and electron interaction M.C. precedentedly low disorder, which have become an ideal laboratory in which to study many-particle physics in lower dimensions.

We numerically study the quantum Hall effect (QHE) in bilayer graphene based on tight-binding model in the presence of disorder. Overview; Fingerprint; Abstract. RIS. Abstract: The quantum Hall conductance of a disordered two-dimensional gas of non-interacting electrons is re-examined for its integrity against disorder in the limit of no mixing between different Landau levels. BibTeX For corporate researchers we can also follow up directly with your R&D manager, or the information Because of the topological constraint, the Fermi arc at a single surface has an open Fermi surface, which cannot host the quantum Hall effect. In particular for 2D electrons in a magnetic field the discoveries have been stunning: An abundance of new energy gaps exists where one ex-pected none. The magnetotransport properties of disordered ferromagnetic kagome layers are investigated numerically.

Instead, we show that the occurrence of a quasi-particle Wigner Crystal (QPWC) for sufficiently small $|\nu-\nu^\star|$ results in a quantized Hall plateau, even in the absence of disorder.
