Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly ...

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 ...

Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect. Researchers at the ...

A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated, validating a recent theoretical prediction.

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 ...
