How can a structure hold together if its individual components are actually repelling one another? An international research team has now demonstrated one example of such a highly excited exotic quantum state of matter. Researchers from the University of Bonn played a major role in the study. The findings have now been published in the journal “Nature.”
The international Belle II collaboration has elected Florian Bernlochner, Professor at the Physikalisches Institut of University of Bonn, as its next spokesperson. This role is of central importance to the collaboration. Starting in the summer of 2025, under his leadership, Belle II will prepare for an upgrade and collect data at unprecedented collision rates. Belle II plays a key role in the planned Excellence Cluster "Color meets Flavor".
ProMaster is a pilot study for a extensive, conceptional development of the Bachelor Physik and the Master of Physics.
As part of its efforts to strengthen top-level research, the German Research Foundation (DFG) funds a number of consortia known as Collaborative Research Centers (CRCs), some of which are implemented by several universities working together."OSCAR" will also continue to receive funding.
Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access. The study has been published in the journal “Nature Communications.”
Dr. Julian Schmitt from the Institute of Applied Physics at the University of Bonn has been presented with the Industrie-Club Düsseldorf’s Science Award for 2024 in recognition of his outstanding work studying quantum gases of photons. The accolade is worth €20,000.
Today, the Euclid Consortium publishes the first scientific publications on observations with the Euclid space telescope. In a first early observation phase, some scientifically spectacular results have already been achieved. These give a glimpse of the unprecedented capabilities of the telescope, which is expected to produce over the next few years one of the most accurate maps of the evolution of our Universe. All fifteen publications will be available on the arXiv preprint server from tomorrow on. Once the peer review process is complete, they will also appear in a special issue of the journal “Astronomy & Astrophysics.”
Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved by an international team of researchers from Germany, Turkey, the USA, China, South Korea and France using the new method of wavefunction matching. As an example, the masses and radii of all nuclei up to mass number 50 were calculated using this method. The results agree with the measurements, the researchers now report in the journal “Nature”.
