Relaxor ferroelectrics are significant for both pure science and for practical applications, since they are an essential ingredient of various electroceramic components. The Spherical Random Bond-Random Field (SRBRF) model, which has been developed in the framework of this research program, has attracted the attention of scientific community as witnessed by the number of citations, as well as by many reports and invited talks at international conferences. Three articles from this field represent three most cited papers among all contributions in this Report. The research on relaxors has become part of two international projects (Collaborative Linkage Grant) sponsored by NATO. From the purely scientific point of view, the study of cellular automata is of essential importance as it represents a simplified version of complex dynamic systems and thus makes them amenable to numerical analysis. The parameters of stochasticity in cellular automata, studied in this program, represent a link between the primary process and the background processes. A number of new phenomena caused by the stochasticity of local rules are important for theoretical understanding of complex systems, for example, the analogy with directed percolation. The structure of domains in ferromagnets and ferroelectrics is the essential physical characteristic, upon which their tehnological applicability is based. Thus we have conquered the theoretical knowledge, which represents the basis for a corresponding applied project. The model of growth and structure of the World Wide Web (WWW) developed within this program has attracted the attention of international community. This is evident from a number of citations, including those in the book "Evolution of Networks", which appeared in 2003 at Oxford University Press, as well as by many invited talks at international meetings. An article about our model of WWW has appeared in the Internet journal "Technology Research News" (Boston), which presents new scientific accomplishments that are potentially applicable for tehnological purposes. Recent investigations have shown that modern digital networks have a scale invariant structure of links. Knowledge of the distribution of current and voltage in these networks is of crucial importance for a successful design of these networks, depending on their designated purpose. The theory of strongly correlated electrons remains a central scientific problem in modern condensed matter theory. In view of the fact that standard perturbation theories often break down due to strong correlations, the development of new analytic and numerical methods is of crucial importance to this field. An example is the numerical method developed here (J. Jaklič in P. Prelovšek, Phys. Rev. Lett. 77, 892 (1996)), which is currently one of a few methods that make it possible to describe the termodynamic properties as well as the dynamic response of strongly correlated electron systems. The unravelling of mechanism of high temperature superconductivity is one of the key unsolved problems in condensed matter physics. Our active collaboration in this field resulted in the organization of an international conference in Bled, supported by NATO. The proceedings appeared in the book "Open Problems in Strongly Correlated Electron Systems", edited by J. Bonča, P. Prelovšek, A. Ramšak, and S. Sarkar, NATO ARW, Sci. Ser. II, Vol. 15, Kluwer, Dordrecht, 2001. The persistent decrease of the dimensions of electronic components has lead to systems of the size of a few nanometers, whose functioning can only be understood on the basis of quantum phenomena. One of the key properties of these systems is the electric conductivity, and understanding it is essential for further development. Investigations of surfaces of solids and ultrathin metal layers are of prime importance in the development of nanotechnologies as well as of substrates for microelectronic elements and catalysts.
