PHY2403F:

Quantum Field Theory I

Instructor: Michael Luke, MP1116, 8-2985, luke@physics

Grader: TBD

Time & Place: TBD

Piazza: We will be using www.piazza.com for homework, updates, etc. All registered students will receive an email inviting them to register.

Evaluation: Problem Sets: 60% (roughly every 2 weeks), Final Exam (take-away, 9 AM - 5 PM): 40%.

References: The primary reference for this course is the lecture notes. There is no required text, but (particularly if you are interested in taking PHY2404S in the spring), I recommend you purchase Peskin & Schroeder, An Introduction to Quantum Field Theory (available at the bookstore). Some other references are given here.

Topics:

1. Introduction: notation, conventions. The need for a multiparticle formulation of relativistic QM.

2. Canonical quantization of free scalar field theory.

3. Symmetries and conservation laws.

4. Interacting fields: Feynman diagrams and the S matrix; cross sections, decay widths and phase space.

5. Spin 1/2 fields: Spinor representations, Dirac and Weyl spinors, Dirac equation. Canonical quantization of the Dirac field. Spin and statistics.

6. Vector fields and quantum electrodynamics.
