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 framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related ...

Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely ...

The quantum anomalous Hall effect (QAHE) is one of the most important phenomena in condensed matter physics, holding significant promise in low-energy-dissipation electronics that could possibly ...

A new framework for understanding the non-monotonic temperature dependence and sign reversal of the chirality-related ...

A team of researchers led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has ...

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

Scientists have uncovered a previously unthinkable state of matter that challenges decades of assumptions ...

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 ...
