Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an ...

Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly ...

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing ...

Interactions between electrons in solids often lead to effects that go beyond simple, intuitive pictures of what should be possible. One example stems from the Hall effect, which describes how the ...

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 ...
