"Theory of Superconductivity is considered one of the best treatments of the field. This monograph, by Nobel Prizewinning physicist J. Robert Schrieffer, has been reprinted because of its enduring value as the introduction to the theory of superconductivity. Based on a series of lectures presented by the author at the University of Pennsylvania, the fundamentals of the microscopic theory of superconductivity are stressed as a means of providing the reader with a framework for the literature in which detailed applications of the microscopic theory are made to specific problems. It also serves as a foundation for the more recent developments in this active field."--back cover
