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.

    Light and matter. Photonics scientist to occupy the cluster's first junior professorship

    Since a Nature article in 2018, experts have been looking forward to photonic quantum physics from Würzburg. Sebastian Klembt played a key role in the presentation of the first topological isolator made of light and matter. The scientist has been the first junior professor in the Cluster of Excellence since November 2020.

    Find a Needle in the Haystack: A New High-Throughput Method for Magnetic Quantum Materials

    With the help of a novel algorithm, magnetic topological compounds can now be searched for automatically. The computer method developed is considered a milestone for research into topological materials and paves the way for systematic identification of such materials, which have so far only been determined on a case-by-case basis.

    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.
