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.

    “Kitty Q” on the prowl for prizes: Mobile game created by the Würzburg and Dresden universities receives three awards in one day

    Three awards in one sweep: the creators of the mobile game app “Kitty Q” and its follow-up project “QUANTube” from the Würzburg-Dresden Cluster of Excellence ct.qmat had every reason to be excited this Wednesday, Sept. 21. Attending two parallel award ceremonies in Leipzig and Berlin, they took home a total of three awards for outstanding science communication and creative science marketing.

    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.

    A ‘fast lane’ for electrons

    The study of ultra-pure materials still has many ways to surprise and delight! For delafossite metals it was shown that wires sculpted from the same single crystal have very different resistivities depending on the angle at which they are cut. From the fundamental physics point of view, the laws of bulk resistivity are being broken.
