Researchers have overturned a century-old physics rule about magnetic field detection. They engineered a custom quantum material to trigger the Hall effect sideways. This breakthrough allows a single ...

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 ...
In a new breakthrough, researchers have used a novel technique to confirm a previously undetected physics phenomenon that could be used to improve data storage in the next generation of computer ...
Our data-driven world demands more—more capacity, more efficiency, more computing power. To meet society's insatiable need for electronic speed, physicists have been pushing the burgeoning field of ...
The fractional quantum Hall effect is one of the most striking manifestations of strong electronic correlations and topology, traditionally requiring intense magnetic fields. Recently, experiments ...
Researchers have discovered a “layer” Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion ...
Germanene undergoes a topological phase transition and then becomes a normal insulator when the strength of an applied electric field is dialed up. Graphene’s valence and conduction bands meet at a ...
