The group “Micro Structured Quantum Matters” at MPI-CPfS develops microscopic electric conducting paths made of quantum materials to understand their physical properties and to test possible applications in new types of electronics. In cooperation with US scientists, they succeeded in showing a rare state in microchips in which electrons move together. That state is called “electronic nematicity”. It occurs in high magnetic fields in a layered metal made of cerium, rhodium and indium, called CeRhIn₅. In an article published in the journal “Nature”, the scientists point to a new approach of understanding the link between electronic nematicity and superconductivity. Electrons move together in the superconductivity as well and links between the two phenomena were assumed for a long time. more
