Welcome to the research area Strongly Correlated Electron Systems at the Physik-Department (formerly institute E21), comprising the chair of Prof. Peter Böni and the group of Prof. Christian Pfleiderer. Scientific activities covered at our institute include the fundamental properties of magnetic and superconducting materials (bulk compounds and thin films), materials science and a few selected problems in particle physics. The institute has a long tradition in neutron related research, notably the development of state-of-the-art neutron scattering techniques. Amongst other contributions we provide the scientific partnership of TUM for the beam lines Reseda, Mira, Antares and Nepomuc at FRM II. In addition we operate a number of laboratories at the Physik-Department that are focussed on studies of bulk properties under extreme conditions, materials preparation and materials characterisation.
