Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of ...

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 ...

Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It's based on the ...

Electrons are influenced by a magnetic field display known as the quantum Hall effect (QHE), which helps scientists make hyper-accurate measurements. Now, scientists have observed a similar behavior ...

Discover how physicists are manipulating electrons in novel ways to unlock potential breakthroughs in quantum computing and ...
