Introduction to Quantum Field Theory PHYS 812 (3)
A first course in relativistic quantum field theory (QFT), mainly quantum electrodynamics (QED). Canonical quantization of the Klein-Gordon, electromagnetic, and Dirac fields; gauge freedom; Feynman diagrams and rules, with applications to scattering cross sections and pair creation; renormalization, with applications to the anomalous magnetic moment of the electron and the Lamb shift. Prerequisite: PHYS 810 or equivalent.
