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.

    Whirlwind in the material: Dresden physicist wins prize for world's first image of a 3D magnetic field

    A Dresden research team led by solid-state physicist Dr. Axel Lubk has succeeded in imaging the magnetic field of tiny magnetic nanovortices - called skyrmions - in three dimensions with a resolution of seven millionths of a millimeter. This is the first time ever that this has been achieved.

    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.

    Coffee, networking and, above all, physics - ct.qmat's hybrid in-person retreat

    Highly motivated speakers, a buzz of voices in the foyer, and lively discussions about the presentations and the posters on display: More than 100 participants attended the first on-site Cluster Retreat–and the second one since the launch of the Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter in 2019– in the placid town of Merseburg from March 23 to 25, 2022. A further 30 retreat guests joined virtually.
