Outline:   Postulates of Quantum Mechanics [a review using Dirac notation] - System description (Schrödinger's equation; eigenvalues and eigenfunctions), hermitian operators (and observables), wavefunction expansion, measurement (expectation values, uncertainty relations and commutators), reduction, time evolution Schrödinger's Equation in 3-Dimensions - Coordinate representations for 3-D wave mechanics, particle in a 2- and 3-D box (degeneracy), 2-D harmonic oscillator, two particle systems (separation, reduced mass), the exchange operator and identical particles (fermions and bosons) Orbital Angular Momentum - Introduction to the angular momentum operator (particle on a ring), angular-momentum/angle uncertainty relation, the cylinder potential, angular momentum eigenvalues, the vector model, spherical harmonics, the operator method, angular momentum matrix operators Central Potentials - The Hamiltonian in spherical coordinates, the spherical box, the spherical square well (deuteron), the linear potential The Hydrogen Atom - Eigenvalues of the Coulomb potential (E < 0), radial eigenfunctions (Laguerre polynomials), complete spherical wavefunctions Stark and Zeeman Effects - The Stark effect and electric polarizability (non-degenerate and degenerate perturbation theory), electrons in a magnetic field (normal Zeeman effect, etc.) Spin States and Matrix Operators - The Stern-Gerlach experiment, spin matrix mechanics (spinors, Pauli matrices, the transformation matrix), addition of orbital and spin angular momentum (Pauli Principle, spectroscopic notation, etc.) Time-Dependent Perturbation Theory - General formalism, periodic perturbation (Fermi's Golden Rule), transitions in atoms (the dipole approximation and selection rules) Scattering Theory - Scattering amplitude, cross sections, Born approximation, partial wave expansion, applications (e.g. Rutherford scattering) Other Applications of Quantum Mechanics [if time permits!] - the ammonia molecule (two-state matrix mechanics), masers and lasers, fine structure of hydrogen, helium, SQUIDs
