Frontiers in Physics Serie

The book presents various theoretical methods that enhance the application of statistical mechanics in material science. It focuses on how these approaches can be utilized to understand and analyze the properties and behaviors of materials, providing valuable insights for researchers and practitioners in the field. Through detailed explanations, it bridges the gap between theory and practical application, making complex concepts accessible for better comprehension and implementation in materials research.

An Introduction to Quantum Field Theory is a textbook intended for the graduate physics course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make these subjects accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a discussion of the physical principles that underlie the fundamental interactions of elementary particle physics and their description by gauge field theories.
