Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective ...
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 ...
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 ...
(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 carried out an experiment that realizes a new kind of quantum standard of resistance. It's based on the Quantum Anomalous Hall Effect. The precise measurement of electrical resistance is ...
Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...
A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster and ...
