Introduction to Quantum Field Theory

Catalog description

This course provides a comprehensive introduction to quantum field theory (QFT), a fundamental framework for understanding not only particle physics but also modern condensed matter physics. Topics covered include the basic concepts of fields, symmetries, Noether currents, and their roles in physical laws, as well as the formulation of QFT using the path integral approach. Perturbation theory, in terms of the Feynman diagram, will be covered in detail. The course emphasizes both theoretical understanding and practical techniques, laying the groundwork for advanced study in condensed matter physics, particle physics and statistical mechanics.
