"This book, with reasonable size, gives a general view of the physics of condensed matter with two main purposes in mind: firstly, to display a coherent and clear picture of classical simple models of crystalline solids, and secondly, to introduce modern topics in a form as simple as possible. It is written in eighteen chapters which are almost self-contained. Furthermore, all keywords of condensed matter are dealt with and expanded in a detailed manner: crystals, phonons, electrons, solids, semiconductors, electronics, spintronics, diamagnetism, paramagnetism, superconductivity, fermions, nanoclusters. This is a standard textbook designed for a one- or two-semester graduate course." --Zentralblatt MATH 1222-1
