Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...
A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...
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 many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...
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 ...
A group of scientists has created a quantum material where electricity can flow without losing energy as heat. Until now, this was only seen in ...
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 ...
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 ...
The Quantum Hall Effect was first observed in 1980 by Klaus von Klitzing, for which he was awarded the Nobel Prize in Physics in 1985. It occurs in two-dimensional electron gases found in ...
A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control ...
