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.

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

    Elena Hassinger has taken on the Chair of Low-Temperature Physics of Complex Electron Systems within 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.

    New fur for the quantum cat: Entanglement of many atoms in a quantum material discovered for the first time

    Be it magnets or superconductors: materials are known for their various properties. However, these properties may change spontaneously under extreme conditions. Researchers at the Technische Universität Dresden and the Technische Universität München have discovered an entirely new type of such phase transitions. They display the phenomenon of quantum entanglement involving many atoms, which previously has only been observed in the realm of few atoms. The results were recently published in the scientific journal Nature.
