In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles ...

A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without ...

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 was first observed in 1980 by Klaus von Klitzing, for which he was awarded the Nobel Prize in Physics in 1985. It occurs in two-dimensional electron gases found in ...

When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting states of matter, such as fractional quantum Hall liquids. These are exotic ...

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 ...
