Welcome to ct.qmat

We are the Cluster of Excellence ct.qmat – Complexity and Topology in Quantum Matter. Established in 2019, the Würzburg-Dresden Cluster ct.qmat is a leading international center for research on topological and complex quantum matter. Our aim is to develop a deep understanding of quantum phenomena in general and to identify materials in which those phenomena are observed in the laboratory. This is supported by educating and attracting top-level students and scientists as well as by supplementing infrastructure in both Würzburg and Dresden.

    Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator

    Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers from the Cluster of Excellence ct.qmat have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10.

    New quantum professor in Dresden: With record low temperatures into the hotspot of solid state physics

    Elena Hassinger has been appointed Professor of Low-Temperature Physics of Complex Electron Systems at the Cluster of Excellence ct.qmat. The professorship has been newly established at TU Dresden. The researcher is an expert in solid-state physics at very low temperatures down to 0.01 Kelvin (-273.14 °C). She studies unusual quantum phenomena that only occur in the freezing cold, with the focus currently being on cerium rhodium arsenic (CeRh2As2) – a promising unconventional superconductor.

    More quantum physics, please! Teachers and scientists meet in Dresden to discuss new ideas for school curricula

    The ct.qmat Cluster of Excellence at the Julius-Maximilians-Universität Würzburg (JMU) and the Technische Universität Dresden (TUD) has embarked on a cooperation with the German Network of Excellence of STEM schools, MINT-EC. The aim is to incorporate the latest quantum physics research findings into the school curriculum as quickly as possible. Teachers from secondary schools from all over Germany are now meeting with the scientists in Dresden. At the center of the exchange are the research topics of ct.qmat and a revolutionary approach of teaching quantum physics through play: gamification, for which the award-winning games app “Kitty Q – A Quantum Adventure” serves as a trailblazing example.
