Summary
The course introduces the most important aspects of non-relativistic quantum mechanics. It includes the fundamental
postulates of quantum mechanics and their applications to square wells and barriers, the linear harmonic oscillator
and spherical potentials and the hydrogen atom. The remarcable properties of quantum particles and the resulting
macroscopic effects are discussed.
