In this accessible introduction for students taking courses on superconductivity, solid state physics, and condensed matter physics, Fossheim and Sudbo>, both affiliated with the Norwegian University of Science and Technology, bring together major developments that have occurred in the field of superconductivity over the past 20 years. Featuring chapter problems, examples, and brief interviews with key Nobel Laureates in the field, the text guides students from basic physics of superconducting materials and the Ginzburg-Landau theory, to more advanced theory, small-scale applications, superconducting wire and cable technology, and historical developments.
