Researching tomorrow's technology today - this idea is at the heart of physics research at Paderborn University. The focus is on modern key technologies such as optoelectronics and photonics, the associated development of new types of components - including for quantum computers - and research into new materials. The profile is supplemented by many-particle and solid-state theories as well as theoretical quantum systems. Research in Paderborn is interdisciplinary: physicists work together with scientists from chemistry, mathematics and computer science, among others. The research in the Department of Physics is rounded off by the didactics of physics and the didactics of physical education, which deals with the promotion of learners of all ages and the effect of innovative teaching concepts at school and university.
