Relaxor ferroelectrics are used as elements for electroceramic components, such as condensers, ultrasonic transducers, and precision actuators for optical systems. In Slovenia, the development of electroceramic materials is carried out by one of the laboratories at Jožef Stefan Institute. The laboratories for dielectric spectroscopy and nuclear magnetic resonance are engaged in the characterization and determination of the structure of relaxors. Theoretical models developed in the framework of the present research program represent the basis for a better understanding of the processes occurring in relaxors, and are thus indispensible in designing new experiments and in data analysis. This research has so far been included in two international projects sponsored by NATO. Theoretical investigations of networks, their structure, and processes on networks are of prime importance for risk managment in banking and communication networks as well as in other areas. New knowledge accumulated in the course of this program will be applied in collaboration with research groups in Slovenia (investigation of social networks) and in the framework of European Action Cost, P10 "Physics of Risk", as well as in bilateral projects between Slovenia, Austria, and /or Great Britain. Since our research on complex systems is of basic character, its importance for Slovenia on a scientific level parallels that for the world in general. The impact of our work as measured by the number of citations and invitations to various conferences contributes to Slovenia's recognizability in international scientific circles. Knowledge of statistical physics of complex systems and nonequilibrium phase transitions gained in these investigations has attracted many successful collaborations with experimental groups, in particular with the Department for Complex Materials at the Jožef Stefan Institute, as well as with foreign research groups through the NATO project "Modelling Internet Traffic on Random Networks". In the field of surface physics there has been an international collaboration with a research group in France. Physics of surfaces is also one of the activities carried out by experimental groups at Jožef Stefan Institute and Nova Gorica Polytechnic. Experimental investigations of high temperature superconductors are being conducted in the laboratory of optical spectroscopy at Jožef Stefan Institute. In the field of the theory of strongly correlated electrons there has been an intense international collaboration with several international projects, such with USA, Switzerland, Italy, Great Britain, and Germany. New numerical methods have been developed, which are applicable to various fields of physics and technology. The group is among the most intensive users of computational capacities for scientific purposes in Slovenia, and is transfering its experience to other potential users.
