Science and research work concentrate on mathematical physics and experimental nuclear and sub nuclear physics, but also on theoretical physics, statistical physics, quantum optics and quantum information, computational physics and plasma physics. In all these areas the department supervises PhD students. Science and research activities of the Department are developed in co-operation with foreign partners, science and research centres (CERN, Fermi lab, GSI) and institutes of the Czech Academy of Science. The Department co-operates closely with the Doppler Institute and develops mainly mathematical physics and other related branches. Co-operation in technology transfer with leading enterprises is developed in the Centre of Excellence. Integration of social sciences and humanities into teaching about energy is the aim of the Erasmus+ Teachener project.
