Introduction to Quantum Field Theory PHYS 812 (3)
A first course in relativistic Quantum Field Theory (QFT), specifically Quantum Electrodynamics (QED). The basic formalism underlying QED is developed, generalizing the canonical quantization procedure of Schroedinger quantum mechanics. Feynman diagrams and rules are derived and applied at leading order to several fundamental processes. An introduction to ultraviolet infinities and the renormalization of QED is given. Renormalization is illustrated by calculations of the anomalous magnetic moment of the electron and the Lamb shift. Prerequisite: PHYS 810 or equivalent.
