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.

Faculty IV's 2026 Annual Celebration

Natural Sciences and Technology School Annual Celebration: Sunshine, a Red Carpet, and Lots of Applause for Up-and-Coming Scholars

The School of Science and Technology at the University of Siegen celebrated its graduates and newly minted Ph.D. recipients in a festive setting. At the annual celebration in the Apollo Theater, the focus was on the achievements of the next generation of scientists—as well as awards for outstanding research and dedicated teaching.

The conditions could hardly have been better: Under bright sunshine and walking across a red carpet, guests streamed into the Apollo Theater. The anticipation for the highlight of the day—the ceremonial presentation of diplomas—was palpable. Even before the event began, many graduates took advantage of the photo backdrop featuring the sculpture of the faculty logo to take commemorative photos in their academic gowns and doctoral caps.
