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 ...

Study finds photons can show a quantum Hall effect under strong fields
Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall ...

Experiment shows light can mimic the quantum Hall effect
Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...
In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...
