Emphasis is placed on analogies between the various systems rather than on advanced or specialized aspects, with the purpose of illustrating common ideas within

The book is an introduction to quantum field theory applied to condensed matter physics. The topics cover modern applications in electron systems and electronic

For most of the last century, condensed matter physics has been dominated by band theory and Landau's symmetry breaking theory. In the last twenty years, howeve

This book introduces systematically the eigenfunction method, a new approach to the group representation theory which was developed by the authors in the 1970's
