The research of the Department of Condensed Matter Physics is focused on the structure and dynamics of disordered and partially ordered condensed matter at the atomic and molecular level with special emphasis on phase transitions. The purpose of these investigations is to discover the basic laws of physics governing the behavior of these systems, which represent the link between perfectly ordered crystals on one side and amorphous matter, soft condensed matter and living systems on the other. Such knowledge provides the key to our understanding of the macroscopic properties of these systems and is an important condition for the discovery and development of new multifunctional materials, nanomaterials and biomaterials for new applications. An important part of the research program is devoted to the development of new experimental methods and techniques in the field of magnetic resonance, magnetic resonance imaging, fluorescence microspectroscopy, scanning tunneling, electronic and atomic force microscopy, as well as dielectric relaxation spectroscopy and dynamic specific heat measurements.

The research programme of the Department of Condensed Matter Physics is implemented in close cooperation with the Physics Department at the Faculty of Mathematics and Physics of the University of Ljubljana, the Institute of Mathematics, Physics and Mechanics, the J. Stefan International Postgraduate School and other departments of the ‘Jožef Stefan’ Institute. The Department also has close historical ties with research centres and universities abroad.

The Department of Condensed Matter Physics is organised into three research groups and four infrastructure centres, which provide technical support for the groups.
