Chiral crystals that have a distinct handedness have recently emerged as one of  the most exciting new classes of topological materials. An international research team from institutions in Germany, Switzerland, United Kingdom, and China has now demonstrated that their crystal handedness directly determines how quasiparticles propagate and scatter at impurities in such materials. The study, published in the journal Nature Communications, represents a significant advance towards novel chiral electronic devices. mehr

In topological materials, electrons can display behaviour that is fundamentally different from that in ‘conventional’ matter, and the magnitude of many such ‘exotic’ phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached — and controlled — in a real material. mehr

Electrons in “chiral crystals”, solid-state materials with definite “handedness”, can behave in unexpected ways. An interdisciplinary team from research institutions in Germany and China has realized now a theoretically predicted peculiar electronic state in a chiral compound, PtGa, from the class of topological materials. The study which was published in the journal Nature Communications allows a fundamental understanding of the electronic properties of this novel semimetal. mehr

The research teams of Hao Tjeng from the MPI-CPfS, Andrea Severing from the University of Cologne, Antoine Maignan from CRISMAT Laboratory Caen, and Maurits Haverkort from the University of Heidelberg have succeeded in determining the electronic orbital that is responsible for the Ising magnetism in Ca3Co2O6. A direct image of the donut-shaped orbital has been made using the new Max Planck end-station at German Electron Synchrotron DESY in Hamburg. mehr
