Relativistic Quantum Field Theory, Volume 2

This volume explores the quantization of classical field theory through the path integral formalism, extending concepts from quantum mechanics to quantum fields.

In Relativistic Quantum Field Theory, Volume 2, the author delves into the quantization of classical field theory through the path integral formalism. The volume starts with a foundational introduction to the path integral approach in non-relativistic quantum mechanics. This initial framework serves as a springboard for extending the formalism to quantum fields characterized by an infinite number of degrees of freedom, which is essential for understanding modern particle physics.

Targeted primarily at students eager to grasp the intricacies of relativistic quantum field theory, this volume remains accessible to those studying condensed matter physics as well. The text not only covers the basics but also ventures into more complex topics, such as the quantization of gauge fields via the Fadeev-Popov method and the treatment of fermionic fields using Grassman algebra. These topics are crucial for readers aiming to comprehend the underlying principles of particle interactions.

As the book progresses, it presents the path integral formulation of quantum chromodynamics, along with its renormalization, which is pivotal in high-energy physics. The author also explores the significant role of topological solutions in non-abelian gauge theories, providing a comprehensive view of modern theoretical physics. Overall, Relativistic Quantum Field Theory, Volume 2 serves as an essential resource for students and enthusiasts alike, bridging foundational concepts with advanced applications.
