Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control ...

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 ...

As quantum Hall effects interact with subtle material vibrations, energy conversion occurs naturally, pointing toward ultra-efficient, low-voltage operation ...

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

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 ...

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 ...

Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...
