Welcome to ctd.qmat 

A Dresden-based research team from the Cluster of Excellence ctd.qmat has discovered a novel transport phenomenon. They found that luminescent quasiparticles can be carried along by magnetic excitations known as spin waves and even accelerated to ultrahigh speeds. This holds promise for future magneto-optical applications. The findings have been published in Nature Nanotechnology.

Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Now—forty years later—a Würzburg-based research team from the Cluster of Excellence ctd.qmat has achieved the first experimental demonstration of KPZ behavior on 2D surfaces in space and time. The results have been published in Science.

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have successfully transferred the topological quantum Hall and spin Hall effects to a hybrid light–matter system using targeted material design.

After 61 stops across Germany, Australia, Austria, and the United States, the traveling exhibition “RETHINKING PHYSICS: A Century of Quantum Mechanics — Time for a Female Perspective!” is drawing to an end. It remains on view at the IFW Dresden through March 10, 2026. A public colloquium will mark the official closing event.

Writing in Nature, an international team of researchers has, for the first time, demonstrated a direct link between electronic states in quantum materials and moiré superconductivity. The theoretical framework was provided by a multi-site team from the Cluster of Excellence ctd.qmat.

Marked by a new focus on dynamics and a distinctive quantum vibe, the Würzburg–Dresden Cluster of Excellence ctd.qmat — Complexity, Topology and Dynamics in Quantum Matter — is entering the second funding period of the German Excellence Strategy of the Federal and State Governments.

The European Research Council (ERC) is supporting a feasibility study led by Professor Yana Vaynzof, Principal Investigator at ctd.qmat, with a Proof of Concept Grant. The €150,000 award will be used to explore a new, high-speed production process for efficient photovoltaic technologies.
