Electron vortices in graphene detected
Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor - such as a metal wire - is connected to a battery, the electrons in the conductor are accelerated by the electric field created by the battery.

Solving physics puzzles with coloured dots
By analysing images made of coloured dots created by quantum simulators, researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity. Up close it looks like lots of coloured dots, but from a distance one sees a complex picture rich in detail: Using the technique of pointillism, in 1886 George Seurat created the masterpiece ,,A Sunday afternoon on the island of La Grande Jatte".
