Modern Quantum Field Theory: A Concise Introduction

This comprehensive and progressive new text presents a variety of topics that are only briefly touched on in other books; this text provides a thorough introduction to the techniques of quantum field theory, which is the theoretical framework for constructing quantum mechanical models of field-like systems or, equivalently, of many-body systems. Covering topics such as Feynman diagrams and path integrals, the author emphasizes the path integral approach, the Wilsonian approach to renormaliz...
