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 ...

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.

Researchers at TU Wien have discovered an unexpected new state of matter in which topological properties emerge even though the usual particle picture of electrons breaks down. The findings show that ...

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 ...
