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.

    “A Wonderful Start” – ct.qmat Launches German-Japanese Research Partnership in Quantum Technologies

    The Würzburg-Dresden Cluster of Excellence ct.qmat hosted a German-Japanese workshop on February 26 and 27, 2024, setting the course for close collaboration between researchers from both countries. Around 70 participants from Germany and Japan convened in Würzburg to discuss their latest findings in quantum physics research. Organized by ct.qmat and supported by the Japan Science and Technology Agency (JST), the workshop delved into areas such as topology, photonics, magnetism, and the dynamics of electron correlation in solids. This exchange of ideas paved the way for joint projects in the coming years.

    Umbrella for Atoms: The First Protective Layer for 2D Quantum Materials

    In a groundbreaking development, researchers at the Würzburg-Dresden Cluster of Excellence ct.qmat have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach. The findings have just been published in Nature Communications.
