Books in the Graduate Texts in Contemporary Physics series

Many experimental discoveries during the last decade, including heavy fermions, fractional quantum Hall effect, high temperature superconductivity, and quantum spin chains, are not readily accessible from the weak coupling point of view.

Intended primarily for graduate students and researchers in theoretical high-energy physics, mathematical physics, condensed matter theory, statistical physics, the book will also be of interest in other areas of theoretical physics and mathematics.

Quantum mechanics was already an old and solidly established subject when the first edition of this book appeared in 1966.
