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 ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though ...

A material cooled near absolute zero produced an electrical signal that physics said should not exist, revealing a new kind ...

Magnetic skyrmions – quasiparticles with a vortex-like structure – show much promise as storage bits for next-generation computer memories and logic devices, but tracking their motion is no easy task.

The film explains the concept of electrons and their role in electric circuits. It describes how electric current is the flow of electric charges, primarily electrons, which cannot be seen but can be ...

At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...
