Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective ...

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 ...

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 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 ...

In one sentence: The spin Hall effect is a phenomenon in which an ordinary electric current flowing through a non-magnetic conductor with strong spin-orbit coupling creates a sideways spin current, ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220007 overviews the photonic spin hall effect. When a beam is reflected (or refracted) at optical interface or propagating ...

Our data-driven world demands more—more capacity, more efficiency, more computing power. To meet society's insatiable need for electronic speed, physicists have been pushing the burgeoning field of ...

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 ...
