Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Researchers in China have observed a novel version of the Hall effect in a single layer of tungsten selenide (WSe 2). The result, which they obtained by applying strain to a sample of the ...

The fractional quantum Hall effect is one of the most striking manifestations of strong electronic correlations and topology, traditionally requiring intense magnetic fields. Recently, experiments ...

Researchers have discovered a “layer” Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion ...

German Nobel laureate Klaus von Klitzing said AI is “conservative” and should remain a tool for human-led research during a ...

Bilayer materials with layer‑locked Berry curvature dipoles can toggle their nonlinear Hall response under an applied gate field, offering a pathway to new nonlinear quantum devices Stained glass ...
