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.

    Quantum honey from black holes

    Researchers of the Cluster of Excellence ct.qmat have proposed a new quantum material in which electrons move as a viscous fluid–like a kind of quantum honey. If scientists succeed in producing the material in sufficient purity, the effect will be three times stronger than in the “miracle material” graphene.

    Superconductors with ‘zeitgeist’ – when materials differentiate between the past and the future

    Physicists of the Cluster of Excellence ct.qmat have discovered spontaneous static magnetic fields with broken time-reversal symmetry in a class of iron-based superconductors. This exceptional property calls for new theoretical models and may become important in quantum computing. The research results have recently been published in the scientific journal Nature Physics.

    A funnel of light

    The group of Professor Ronny Thomale at the University of Würzburg, in joint collaboration with the experimental optics group of Professor Alexander Szameit in Rostock, has developed a light funnel system which might inspire new generations of hypersensitive optical detectors and sensors for future information and communication technologies. Their results have just been published in the “Science” magazine.

    MnBi2Te4 – the name of the first antiferromagnetic topological insulator

    A large consortium of international and interdisciplinary research teams involving Technische Universität Dresden, Leibniz IFW Dresden and Julius-Maximilians-Universität Würzburg has discovered a new type of bulk quantum material with intrinsically magnetic and topological properties. The new material is called manganese-bismuth telluride (MnBi2Te4) and is promising for applications in antiferromagnetic spintronics and quantum technologies. The results of the research work are published in the renowned journal Nature.
