Welcome to the Department of Physics

The focus of our research is on current topics in the fields of solid state physics, quantum optics and particle physics. In our working groups, 22 professors work together with students and scientists to research current issues from experiment and theory. Numerous international collaborations underline the high visibility of our research.

The close cooperation between the student council and the university guarantees excellent support for our students and a high quality of teaching. The excellent relationship between lecturers and students enables us to provide individual support. Thanks to the close integration of teaching and research, our students can gain an early insight into current research projects in the various working groups. We offer special lecture series for interested pupils.

Searching for the Axion with a Giant Magnet

The German Research Foundation (DFG) has approved the construction of the central magnet system for the “BabyIAXO” project by the “Color meets Flavor” Cluster of Excellence at the Universities of Bonn, Siegen, and Dortmund. A total of 6 million euros will be invested in the project. The goal is to search for the axion—a previously undiscovered elementary particle that could solve one of the greatest mysteries in particle physics.
