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–Complexity and Topology in Quantum Matter 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 as they have observed topological phenomena in a circuit system with gain and loss. The theoretical foundation for non-Hermitian topology might enable optronic technologies in the long run.
Cooling is a long-standing technological challenge. Standard cooling cycle based on vapor compression exploits expensive helium gas to reach temperatures near absolute zero. Adiabatic demagnetization known since nearly a century could be a viable alternative if compact and durable paramagnetic materials were available. A team of researchers from the University of Augsburg used their recent experience in creating quantum-disordered magnetic states to design a promising new material for adiabatic demagnetization cooling.
An international research team has made progress towards improved materials for quantum sensor technology. Medicine, navigation and IT could benefit from this in the future.
A German-polish research team from Augsburg, Münster, Munich and Wrocław successfully mixed nanoscale sound waves and light quanta. In their study published in Optica the scientists use an ’artificial atom’ that converts the vibrations of the sound wave to single light quanta - photons - with unprecedented precision. The demonstrated fundamental principle marks an important step toward the development of future hybrid quantum technologies.
The German Research Foundation (DFG) has approved three new Collaborative Research Centres/Transregios (CRC/TRR) at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). The aim of CRC/TRR 305 is to understand the molecular mechanisms behind how metastases form and to develop new treatments for cancer metastases on this basis. In CRC/TRR 306, researchers will be investigating the collective behaviour of quantum systems. In the CRC ‘CLINT’, scientists will pursue a ground-breaking new approach in chemical reaction engineering to create technical catalysts with new properties.
Researchers at the the University of Regensburg and the MPSD in Hamburg have developed a groundbreaking method to detect the dynamics of light on such a small scale with high temporal resolution.
