Informationen zum Autor A S Alexandrov, Nevill Mott Klappentext Written by eminent researchers in the field, this text describes the theory of superconductivity and superfluidity starting from liquid helium and a charged Bose-gas. It also discusses the modern bipolaron theory of strongly coupled superconductors, which explains the basic physical properties of high-temperature superconductors. This book will be of interest to fourth year graduate and postgraduate students, specialist libraries, information centres and chemists working in high-temperature superconductivity. Zusammenfassung Written by experts in the field this book provides an explanation of physical properties of high temperature superconductors based on modern bipolaron theory of superconductivity in clear and accessible language.
