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 ...

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 ...

A new study examined the mechanism governing the nonlinear Hall effect, paving the way for battery-free devices.

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...

The Hall effect is a mainstream direction in the study of condensed matter physics. Recently, the second-order Hall effect that does not require a magnetic field has recently been discovered in ...
