    Using X-rays (green in the picture), researchers have created 3D cinema-like effects on the kagome metal TbV6Sn6. This way, they have succeeded in tracking down the behaviour of electrons (blue and yellow in the picture) and have taken a step forward in the understanding of quantum materials.

    An international team of scientists has succeeded in experimentally confirming a characteristic of topological materials. The Universities of Würzburg and the Dresden with their Cluster of Excellence ct.qmat were involved.

    Three excitons (pairs consisting of an electron and an electron hole) on the topological insulator bismuthene. Due to the honeycomb atomic structure, electrons can only flow along the edges.

    Within the framework of the Würzburg-Dresden Cluster of Excellence ct.qmat, excitons were generated in a topological insulator for the first time. A breakthrough in quantum research, based on material design from Würzburg.
