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.

    "Construction manual" for quantum materials

    Physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat have discovered a minimum distance at which electrons in wires made of quantum materials must flow in order to conduct electricity in a dissipationless manner. The research results have been published in the journal Physical Review Letters.

    Topolectrical circuits: A new direction of topological research is ready for take off

    Through a recently developed experimental platform, topological matter can be realized in a fast, cost efficient, and versatile way. It was only about two years ago that researchers of the Cluster of Excellence ct.qmat realized "Topolectric Circuits" and did important pioneering work on their conceptualization for synthetic topological matter. Another breakthrough has now been achieved by the team led by Würzburg physicist Prof. Dr. Ronny Thomale.

    Electrons waiting for their turn: new model explains 3D quantum material

    Scientists from the Cluster of Excellence ct.qmat have developed a new understanding of how electrons behave in strong magnetic fields. Their results explain measurements of electric currents in three-dimensional materials that signal a quantum Hall effect. These results have just been published in the scientific journal Nature Communications.

    It's all about the surface

    The extraordinary material manganese bismuth telluride is the first topological insulator to exhibit a number of spectacular physical effects due to its internal magnetic field. Now, researchers of the Cluster of Excellence ct.qmat found out which atomic layer has to be on the surface for this to happen. This makes it possible to better control the properties of this quantum material and brings it a little closer to everyday use. For the future, this promises a more energy-efficient technology.
