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 ...

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 team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without ...

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 ...

(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 ...

A research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of Salerno in Italy has discovered that thin films of elemental bismuth exhibit the so-called non-linear Hall ...
