8.323 Relativistic Quantum Field Theory I (Spring 2023, MIT OCW): Lecture 18

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)

Lecture 18 - Discrete Symmetries

Definition of discrete symmetries, discrete spacetime symmetries: parity and time-reversal, antilinear and anti-unitary operators, charge conjugation, discrete symmetric transformation of a scalar field, transformation of a Dirac field under parity, time-reversal and charge conjugation, Grassman variables/numbers.
