This book covers quantum field theory at an introductory level appropriate for graduate students in physics. The first volume aims to allow students to begin their research in fields using quantum field theory, such as particle physics, nuclear physics, cosmology and astrophysics and condensed matter physics. The key areas the book explores include free (noninteracting) fields, field quantization, interacting fields, Feynman diagrams, scattering, cross sections and decay rates; renormalization; symmetry, symmetry breaking and Goldstone bosons. Graduate students studying particle, nuclear, and condensed matter physics are the key audience for this volume. It will also be useful to researchers looking for a modern overview of quantum field theory.

Key Features:

• Emphasizes key concepts and techniques of field theory common across particle physics, nuclear physics, condensed matter physics and cosmology.
• Examples and problems from many areas of modern physics.
• Each chapter includes worked examples and exercises within the main body of the text, with more substantial problems at the end of each chapter.
