Proceedings Models And Phenomenology For Conventional And High Temperature Superconductivity

The search for microscopic models to explain the many superconducting substances has introduced seminal concepts and techniques in many-body physics and in statistical mechanics. The complexity of the high-temperature superconductors has required a remarkable refinement of experimental techniques in order to allow a reliable characterization of the samples, and is partly the reason why so many different microscopic models have so far been proposed. This Enrico Fermi Course on Superconductivity was provided an up-to date presentation of selected experimental and theoretical theories on the (so called) conventional superconductivity and on the high temperature superconductivity. The attention was focused on those reliable measurements which are expected to provide the theory with key constraints, viz: Raman and Infrared Spectroscopy, Nuclear Spin Resonance, Angular Resolved Photoemission Spectroscopy, transport measurements, Josephson effect. The lectures devoted to the overview of the BCS theory and to the discussion of minimal models and of the crossover from BCS to Bose-Einstein condensation may be particularly useful. The remaining part of the program was shared between phonon and non-phonon based mechanisms. On the one hand, special emphasis has been devoted to the breakdown of the Migdal theorem and to polaronic theories. On the other, the book contains an overview of strongly correlated electron theories, including magnetic interactions. A survey of the physics of vortices completes the theoretical part of the lectures.

This proceedings contains the works of both experimental and theoretical aspects of high temperature superconductivity with special emphasis on the results obtained by nuclear methods (e.g. neutron scattering, μSR, positron annihilation and Mössbauer spectroscopy).

This volume covered all topics of current interest in High Temperature Superconductivity with emphasis on experimental and theoretical physics. It includes chemical aspects, material and applications of HTc

The topics of this Conference focus on 1) the optical, electronic, thermal, elastic, magnetic, and transport properties, 2) thin films and single crystals, 3) structural properties and new materials, 4) theoretical aspects of high temperature superconductivity.

This proceedings covers topics on high Tc superconducting materials, their structure and properties, the devices and their applications. It also covers the theoretical studies as well as state-of-the-art developments in high Tc superconductivity.

This is a combined volume of the Proceedings for the Workshop on 'Mechanisms of High Tc Superconductivity' (20 June –29 July) and the Adriatico Research Conference (26 - 29 July) on high temperature superconductivity. It aims to bring together a critical overview of the experimental situation and an in-depth discussion of the various theoretical models proposed to explain the mechanisms for high temperature superconductivity by experts actively involved in high Tc research.
