    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.

    Artistic rendition of a topological array of vertically emitting lasers. All 30 microlasers along a topological interface (blue) act as one, collectively emitting coherent laser light (red).

    Israeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser - a highly effective laser network the size of a grain of sand. The findings are presented in a new joint research paper published online by the prestigious journal Science on Friday, September 24.

    In der Überlagerung von gemessener Elektronenverteilung (links) und dreieckiger Atomstruktur (rechts) wird deutlich, dass die Elektronen (gelb) nicht auf den grauen Indium Atomen sitzen, sondern sich in den leeren Regionen (rot und blau) sammeln und ein Honigwabenmuster bilden. Dieser Effekt macht die topologischen Eigenschaften des Quantenmaterials Indenen besser als die des Wunderwerkstoffs Graphen.

    Researchers from the Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter–have recently conceived and realized a new quantum material. The research results have appeared in the journal Nature Communications.
