This course is an introduction to the more advanced ideas of quantum mechanics. We will begin with the raising and lowering operators of a simple harmonic oscillator, a review of nondegenerate perturbation theory, and a development of degenerate perturbation theory. We then describe time-dependent phenomena in quantum mechanics, including time-ordered products, evolution operators, and perturbation theory. We also briefly describe Fermi's golden rule, the sudden approximation, and the creation of light from atomic hydrogen. Then we move onto Fermionic problems, starting with the creation and annihilation operators and how they apply to simple bandstructure calculations, followed by a thorough discussion of the Hubbard model, which illustrates many different correlated phenomena ranging from antiferromagnetism to ferromagnetism.
