I will assume knowledge of quantum mechanics and electrodynamics at the level of our first year graduate courses. In practice, this means you can solve for the hydrogen and harmonic oscillator spectra; that you know the angular momentum algebra and about Pauli spin matrices; and how Maxwell's equations are invariant under Lorentz transformations. The course will start with a review of these topics.
Although no textbook is required, the book by Bjorken and Drell is a useful reference; another useful book is "Advanced Quantum Mechanics" by J. J. Sakurai. The classic text in this subject is by its inventor, "Principles of Quantum Mechanics" by P.A.M. Dirac. My own favorite treatment is in the first few chapters of "Quantum Field Theory" by Itzykson and Zuber.
There will be no examinations in the course; instead there will be some homework assignments. The course will be graded on a Pass/Fail basis.
