This course is a a general introduction to non-relativistic quantum mechanics, focusing on topics relevant for materials scientists. Topics include: Summary of classical mechanics and electrodynamics. Postulates of quantum mechanics, wave functions, operator formalism and Dirac notation. Stationary-state problems, including quantum wells, tunneling and density-of-states calculations. Harmonic oscillator. Free particle, wave packet, and scattering states. Central potentials and hydrogen atom. Atoms and periodic table.
