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.

One big bang and back

At the Physics Study Day at the Emmy Noether Campus, young people from the region experienced hands-on science in laboratories and lecture halls. In this way, the University of Siegen aims to arouse enthusiasm for science and interest in a possible course of study at an early age.

IHK Siegen prize goes to Lars Maczey for his Master's thesis

PenteQost Spring School of Quantum Sciences

Experience quantum physics up close: From May 22 to 25, 2026 (Pentecost), the 3rd edition of the PenteQost Spring School of Quantum Science will take place at the University of Siegen - in cooperation with the University of Gdansk in Poland. The spring school is an international, interdisciplinary course aimed primarily at Bachelor students. Renowned scientists from all over Europe will introduce the basics of quantum science. Students from all disciplines are welcome to participate through lectures, interactive discussions and group work - prior knowledge of linear algebra and the basics of quantum physics are sufficient as an introduction. Registration is still possible until May 02, 2026.
