A twist connecting magnetism and electronic-band topology

Materials that combine topological electronic properties and quantum magnetism are of high current interest, for the quantum many-body physics that can unfold in them and for possible applications in electronic components. For one such material, physicists have now established the microscopic mechanism linking magnetism and electronic-band topology.

Forgotten property of the electron

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely over...
