The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

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 ...

A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related anomalous Hall effect in highly conductive metals has been developed by scientists ...

A giant anomalous Hall effect (AHE) has been observed in a nonmagnetic material for the first time, as reported by researchers from Japan. This surprising result was achieved using high-quality Cd 3 ...

The quantum anomalous Hall effect (QAHE) is one of the most important phenomena in condensed matter physics, holding significant promise in low-energy-dissipation electronics that could possibly ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...
