Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective ...

Researchers at the University of Würzburg have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall ...

Deliberately breaking crystal symmetry widens topological bandgaps in 2D magnets made from light elements, predicting quantum ...

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 ...

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 ...

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This finding opens up a new range of possibilities for the development of efficient ...
