Mathematical Methods of Many-Body Quantum Field Theory

Mathematical Methods of Many-Body Quantum Field Theory offers a comprehensive, mathematically rigorous treatment of many-body physics. It develops the mathematical tools for describing quantum many-body systems and applies them to the many-electron system. Presenting many recent advances and clarifying difficult concepts, this book provides the background, results, and details needed to further explore the issue of when the standard approximation schemes in this field actually work and when they break down. At the same time, the authors clear explanations and methodical, step-by-step calculations shed welcome light on the established physics literature.
