Prof. Dr. Simon Stellmer's Quantum Metrology research group celebrates the inauguration of the ring laser experiments on Thursday, February 1 from 13:00.

 The new Collaborative Research Center (CRC) "NuMeriQS: Numerical Methods for Dynamics and Structure Formation in Quantum Systems" aims to advance the understanding of dynamics and structure formation in quantum systems. The German Research Foundation (DFG) is setting up the CRC at the University of Bonn to strengthen cutting-edge research. Forschungszentrum Jülich and the Max Planck Institute für Kohlenforschung are also involved. The start is planned for April 2024. Over the next three years and nine months, around eight million euros will flow into the research network. The Transdisciplinary Research Area "Matter" at the University of Bonn supported the creation of the CRC.

New high-tech measurement methods are required to detect new phenomena sought after in particle physics. The University of Bonn Research and Technology Center for Detector Physics (FTD), thanks to its research groups, is a leading developer of such detector technology, employed at research institutions around the world. A ceremony was held for operational start-up of the scientific equipment, attended by numerous high-profile guests. 

The Belle II cooperation project at the Japanese research center KEK is helping researchers from all over the world to hunt for new phenomena in particle physics. The international experiment has now reached a major milestone after a team successfully installed a new pixel detector in its final location in Japan. The size of a soda can, the detector was developed in order to make out the signals coming from certain types of particle decays, that can shed light on the origin of the matter-antimatter asymmetry that has been observed in the universe. The installation ran without a hitch and is a key milestone in the evolution of the experiment and German-Japanese research collaboration.

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics. The publication has now been released in the journal Nature Physics.

Prof. Dr. Simon Stellmer has been awarded a Proof of Concept Grant by the European Research Council (ERC) as part of a program designed to help researchers translate their ideas from previous ERC projects into commercial applications. The grant is endowed with €150,000.

In seeking an explanation to what holds the world together at its core, particle physicists face many unresolved mysteries. The matter and energy we know make up only five percent of the cosmos; but what is the remaining “dark matter” and “dark energy” made of? Why is there so much matter but so little antimatter in the universe? And why do the second most common known particles in the universe, called neutrinos, have such tiny masses? To answer these fundamental questions, the new Clausius Professor Jun.-Prof. Dr. Lena Funcke and her team are developing models beyond the Standard Model of particle physics and applying novel computational methods for calculating model predictions for future experiments. This will be a new research focus at the University of Bonn in the Transdisciplinary Research Area “Building Blocks of Matter and Fundamental Interactions” (TRA “Matter”).
