These proceedings contain some selected topics in high Tc superconductivity. The experimental data presently available on high Tc superconductivity together with some of the existing theories (BCS, bipolarons, anyons, superconductivity by quantum size effect, local pairing) are reviewed.

This volume contains invited and contributed papers of eminent scientists who are deeply involved in the field of strongly correlated electron systems and high-Tc superconductivity. The topics of the papers include the Hubbard model, the t-J model, the polaronic model for high-Tc superconductivity, Fermi liquid and non-Fermi liquid theory, and heavy fermion systems.

The subject of the School is on the theory and phenomenology of 'classical' superconductivity. However, the selection and treatment of the different topics is done in the perspective of the new, 'high Tc'' materials, in order to clarify what is already contained in the BCS frame, and what is not.

This Conference is designed to cover the entire field of current-carrying properties of superconductors, either metallic alloys or the new high-Tc metallic oxides. Related topics will be treated as well as the large scale applications. Topics covered include magnetization and flux behaviour, current transport and critical currents, Josephson junctions and proximity effect, microwave absorption and rf surface resistance, thermal conductivity and specific heat, Hall effect and thermoelectric power, thermal fluctuations and paraconductivity, applications of high-Tc materials.

Advances through carefully conducted quantitative work on well designed, high quality materials characterize the present state of high-temperature superconductivity research. The contributions to this volume present a theoretical and experimental overview of electronic structure and physical properties, including anisotropic features, of high-temperative materials, with a focus on cuprates. In order to enhance the understanding of the mechanisms of superconductivity at high temperatures, this volume is divided into theoretical and experimental parts. The contributions to the two parts correspond to each other, giving readers involved in either area of research activity a reference to findingsof the other. On the other hand, this book gives young physicists high-level information on the present state of research, enhanced by tutorial contributions of leading physicists in the field.
