Course Description
In this course, students learn the basics of non-relativistic quantum mechanics.
The course introduces the concept of the wave function, its interpretation,
and covers the topics of potential wells, potential barriers,
quantum harmonic oscillator, and the hydrogen atom. Next,
a more formal approach to quantum mechanics is taken by
introducing the postulates of quantum mechanics, quantum operators,
Hilbert spaces, Heisenberg uncertainty principle, and time evolution.
The course ends with topics covering the addition of angular momenta, spin,
and some basic aspects of many-body quantum mechanics.
The course will include two lectures per week accompanied by a recitation.
