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 ...

(a) Schematics of the A-A stacking hexagonal lattice. (b) First Brillouin zone and the distribution of the Weyl points. The arrows show their shifts direction by changing the on-site energies of A and ...

Scientists may have finally unlocked the unusual role quasiparticles known as "anyons" play in a pair of quantum experiments ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...
