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 ...
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, ...
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 ...
