“Several theory groups have speculated that analogues of these structures could emerge in quantized anomalous Hall systems, ...

Physicists in Germany have developed a new way of defining the standard unit of electrical resistance. The advantage of the ...

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 study of the AHE in nanotechnology has also led to the discovery of new quantum phenomena, such as the quantum anomalous Hall effect (QAHE). The QAHE is a quantized version of the AHE that occurs ...

Physicists have identified an unprecedented quantum phenomenon that allows precise manipulation of electron spin and ...

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They’re a bit strange: their surfaces conduct electricity, yet their interiors do not, instead acting as ...

Researchers have discovered an innovative way to manipulate electronic properties in a magnetic Weyl semimetal using hydrogen ...

To develop viable spintronics, physicists must understand the quantum properties within ... Hall torque is related to the well-known anomalous Hall effect, discovered by Edwin Hall in 1881.

A unique feature of the Quantum Anomalous Hall Effect (QAHE) is that it can occur without the need for a magnetic field. The operation in the absence of any external magnetic field not only ...

they do not exhibit the quantized Hall conductivity and dissipationless edge states found in QAH insulators. The robust and quantized nature of the QAH effect makes QAH insulators more promising for ...

An international team of researchers led by the Strong Correlation Quantum Transport Laboratory of the RIKEN Center for ...
