High-Temperature Quantum Hall Effect in Graphite-Gated Graphene Heterostructure Devices with High Carrier Mobility [PDF]

Nanomaterials, 2022
Since the discovery of the quantum Hall effect in 1980, it has attracted intense interest in condensed matter physics and has led to a new type of metrological standard by utilizing the resistance quantum.

Quantum Hall effect in a CVD-grown oxide [PDF]

Nature Communications
Two-dimensional (2D) electron systems are promising for investigating correlated quantum phenomena. In particular, 2D oxides provide a platform that can host various quantum phases such as quantized Hall effect, superconductivity, or magnetism.

Half-quantum mirror Hall effect

Nature Communications
We predict a half-quantized mirror Hall effect induced by mirror symmetry in strong topological insulator films. These films are known to host a pair of gapless Dirac cones in the first Brillouin zone associated with surface electrons.

Measuring Hall voltage and Hall resistance in an atom-based quantum simulator [PDF]

Nature Communications
In the Hall effect, a voltage drop develops perpendicularly to the current flow in the presence of a magnetic field, leading to a transverse Hall resistance.

6D fractional quantum Hall effect [PDF]

Journal of High Energy Physics, 2018
We present a 6D generalization of the fractional quantum Hall effect involving membranes coupled to a three-form potential in the presence of a large background four-form flux.

Robust fractional quantum Hall effect in the N=2 Landau level in bilayer graphene [PDF]

Nature Communications, 2016
Electron-electron interactions in many-body systems may manifest themselves through the fractional quantum Hall effect. Here, the authors perform transport measurements in bilayer graphene, and observe particle-hole symmetric fractional quantum Hall ...

Quantum Hall effect: from the drude conductivity model to the Chern-Simons field description

Revista Brasileira de Ensino de Física, 2023
The goal of this article is to introduce the quantum Hall effect (QHE) from its classical roots to the quantum integer and fractional versions. This is a robust phenomenon with topological nature.
