The Fachschaftsinitiative (FSI) is an open group of students advocating for student interests within the physics department. They are represented in the departmental council and various committees, organize orientation weeks for new students, and serve as a constant point of contact for questions regarding studies. Regular meetings are held during the semester, typically announced via email. Responsibilities include coordinating student representatives' work, managing the Cafe XX (student lounge), and providing information about study regulations and processes.
