New quantum professor in Dresden: With record low temperatures into the hotspot of solid state physics
Elena Hassinger has been appointed Professor of Low-Temperature Physics of Complex Electron Systems at the Cluster of Excellence ct.qmat. The professorship has been newly established at TU Dresden. The researcher is an expert in solid-state physics at very low temperatures down to 0.01 Kelvin (-273.14 °C). She studies unusual quantum phenomena that only occur in the freezing cold, with the focus currently being on cerium rhodium arsenic (CeRh2 As2 ) – a promising unconventional superconductor.

Whirlwind in the material: Dresden physicist wins prize for world's first image of a 3D magnetic field
A Dresden research team led by solid-state physicist Dr. Axel Lubk has succeeded in imaging the magnetic field of tiny magnetic nanovortices – called skyrmions – in three dimensions with a resolution of seven millionths of a millimeter. This is the first time ever that this has been achieved.

A ‘fast lane’ for electrons
The study of ultra-pure materials still has many ways to surprise and delight! For delafossite metals it was shown that wires sculpted from the same single crystal have very different resistivities depending on the angle at which they are cut. From the fundamental physics point of view, the laws of bulk resistivity are being broken.

Electron conspiracy in a Japanese lattice pattern: Kagome metals baffle science
The special structure of the atomic lattice of potassium-vanadium-antimony leads to an extraordinary combination of outstanding quantum properties, which have now been demonstrated for the first time and could enable a completely new type of superconductivity. Prof. Ronny Thomale, Würzburg researcher of the Cluster of Excellence ct.qmat, predicted such quantum effects theoretically already ten years ago. The latest experimental results have been published in the journal Nature.

"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 .
