To develop viable spintronics, physicists must understand the quantum properties within ... Hall torque is related to the ...

It's based on the Quantum Anomalous Hall Effect. The precise measurement of electrical resistance is essential in industrial production or electronics -- for example, in the manufacture of high ...

In the late ’80s, the theorist Duncan Haldane, then at the University of California, San Diego, predicted that it might even be possible to see integer plateaus without the aid of an external magnetic ...

This groundbreaking achievement has successfully addressed two crucial challenges in realizing the fractional quantum anomalous Hall effect with photons, providing new means for experimental ...

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

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 ...

Large-gap quantum anomalous Hall insulator materials exhibit a quantum anomalous Hall effect with a relatively large energy gap between the valence and conduction band. These materials should ...

This arrangement allowed the electrons to pass through with only a fraction of their charge, creating the first “fractional quantum anomalous Hall effect” (anomalous here meaning “non ...

the realization of integer and fractional quantum anomalous Hall effect (IQAHE and FQAHE). The research was praised by reviewers as a breakthrough in the field. They also said that the original ...

The quantum anomalous Hall effect (QAH) is slightly different. Here, the effect arises in a material that is already magnetized, and the material’s resistance is quantized even at even at weak (or ...
