The Departement of Physics of the University of Basel is a center for international top-level research in the fields of nano and quantum physics, and cosmology and particle physics. Our students benefit from the excellence in research that offers them an outstanding range of courses supervised by highly talented assistants and renowned professors. Two modern fields of physics make up the focal areas of our department: nano and quantum physics, and cosmology and particle physics. Nano and quantum physics are concerned with the research of structures at the nanometerscale as well as with understanding and controlling the quantum phenomena that occur in the process. Cosmology and particle physics examine the fundamental elementary particles of matter and develop the physical theory of the evolution of the universe. Both fields are connected through quantum physics serving as their underlying basic theory. Driven by new experimental possibilities and theoretical insights, the two fields are currently seeing a rapid development to which we are actively contributing. The research results gained along the way will shape both the scientific world view and the technologies of the future.
