8.323 Relativistic Quantum Field Theory I

8.323 Relativistic Quantum Field Theory I (Spring 2023, MIT OCW). Instructor: Prof. Hong Liu. This course is a one-term self-contained subject in quantum field theory. Concepts and basic techniques are developed through applications in elementary particle physics and condensed matter physics. (from ocw.mit.edu)
