The first antiferromagnetic topological insulator

As part of an international cooperation, the groups of Anna Isaeva (TU Dresden) and Hendrik Bentmann (JMU Würzburg) have discovered a new type of bulk quantum material with intrinsically magnetic and topological properties.

Interacting topological edge channels

The groups of L. Molenkamp and B. Trauzettel  studied the interaction of counterprogagating edge channels for the very first time.

Correlations in the edge channels of Bismuthen

The groups of R. Claessen and R.Thomale predicted and measured two electron correlations in topological protected edge states.

Have fun watching the new video about studying physics in Würzburg.

Welcome to 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.
