Study and research at the Department of Physics and Astronomy

As far as particles of light are concerned, the collective is more important than the individual. When they get to decide between two states, they will favor the one that many of their fellow particles have already adopted. However, this collectivist tendency does not kick in until enough photons have assembled in the same place. These findings, revealed by University of Bonn physicists in a recent study, could aid the development of ultra-powerful laser sources, among other things. They have now been published in the journal “Physical Review Letters.”

As part of the “vielfältig.nachhaltig.digital” initiative, the University of Bonn is promoting the creation of a new module on digital skills in teacher training programs.

The first performances of “Zukunftsenergien – Zukunftsmusik?” (“Energies of the Future—Dreams of the Future?”), or “Phyusical” for short, are set for October 25 and 26 in the Wolfgang Paul lecture hall at the University of Bonn. The new physics musical combines drama, live music and live experiments to produce an energy-packed 75-minute-long show. The “Phyusical” is aimed at an interested audience 12 and over, with no particular prior knowledge required. Written by Dr. Jana Heysel, the musical is performed by members of the Physics Show, a dedicated group of physics students at the University of Bonn led by Professor Herbert Dreiner. It is being funded by the Federal Ministry of Research, Technology and Space (BMFTR) as part of the Science Year 2025, whose theme is “energy for the future.”

With curiosity and excitement, many children explored the world of quantum physics during “Türen auf mit der Maus” on the 3rd of October — from fiber coupling to laser cooling of atoms.
