Many-Body Theory of Condensed Matter Systems

In this primer to the many-body theory of condensed-matter systems the authors introduce the subject to the non-specialist in a broad concise and up-to-date manner. A wide range of topics are covered including the second quantization of operators coherent states quantum-mechanical Green''s functions linear response theory and Feynman diagrammatic perturbation theory. Material is also incorporated from quantum optics low-dimensional systems such as graphene and localized excitations in systems with boundaries as in nanoscale materials. Over 100 problems are included at the end of chapters which are used both to consolidate concepts and to introduce new material. This book is suitable as a teaching tool for graduate courses and is ideal for non-specialist students and researchers working in physics materials science chemistry or applied mathematics who want to use the tools of many-body theory.
