Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum ...

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 ...

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 ...

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing ...

The planar Hall effect is a tabletop diagnostic tool for special quantum properties useful in basic research and ...

Until now, the zero magnetic field Quantum Anomalous Hall effect only occurred at very low currents. This device can change that. The precise measurement of electrical resistance is essential in ...

German Nobel laureate Klaus von Klitzing said AI is “conservative” and should remain a tool for human-led research during a ...

(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 ...
