Physicists at the University of Bonn and the University of Kaiserslautern-Landau (RPTU) have created a one-dimensional gas out of light. This has enabled them to test theoretical predictions about the transition into this exotic state of matter for the first time. The method used in the experiment by the researchers could be used for examining quantum effects. The results have been published in the journal “Nature Physics.”

In her ERC Starting Grant project, “PiCo—Towards constraining the Pillars of our Cosmological model using combined probes”, Assistant Professor Andrina Nicola from the Argelander Institute for Astronomy at the University of Bonn will be exploring two fundamental questions of modern physics: What mechanism gave rise to the primordial fluctuations seeding all the structures seen in the Universe today? And what is the cause of the Universe’s late-time accelerated expansion?

Thousands of light particles can merge into a type of “super photon” under certain conditions. Researchers at the University of Bonn have now been able to use “tiny nano molds” to influence the design of this so-called Bose-Einstein condensate. This enables them to shape the speck of light into a simple lattice structure consisting of four points of light arranged in quadratic form. Such structures could potentially be used in the future to make the exchange of information between multiple participants tap-proof. The results have now been published in the journal Physical Review Letters.

The European nuclear research centre CERN is turning 70, celebrate with us from 14-20 September 2024 at the University of Bonn. The major anniversary of particle physics research in Europe will be celebrated on a big stage in Berlin this week and we would also like to contribute to the celebrations in Bonn with a series of events.

The world's first physics show musical returns to the big stage on August 23 and August 24, 2024. In two entertaining hours, the physics show musical offers the audience live music, live singing and lots of humor, providing interesting facts about our blue planet.

Professor Claude Duhr is the speaker for a new Research Unit for particle physics which DFG will be funding over the next four years. From the Physikalisches Institut, Priv.-Doz. Dr. Florian Loebbert  and Prof. Dr. Albrecht Klemm are also Principal Investigators in the new project.

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.”
