This 1998 book describes the physics of superconductivity and superfluidity; ideal for graduate students and researchers.The Nobel Prize for physics has been awarded twice since 1986 for research into superconductivity and superfluidity. Also, the superfluid phase is expected to occur in hadronic matter, the basic building material of matter itself. Physicists from a wide range of backgrounds are interested in these fascinating phenomena. This book presents all the necessary theoretical and experimental background to the subject at a level appropriate for graduate students and new researchers in the subject.The Nobel Prize for physics has been awarded twice since 1986 for research into superconductivity and superfluidity.

In the first part of the book the author presents the mean field theory of generalized pair condensation. This is followed by a description of the properties of ordinary superconductors using BCS theory. The book then proceeds with expositions of strong coupling theory and the Ginzburg-Landau theory. The remarkable properties of superfluid helium 3 are then described, as an example of a superfluid with internal degrees of freedom. Recent topics in the field, such as the copper-oxide high temperature superconductors and exotic superconductivity of heavy fermion systems are discussed in the final chapter. This book will be of interest to graduate students and researchers in condelĂ
