Welcome to Phys 139B, 2012!

Welcome to the second part of Quantum Mechanics!

In this course, you will learn how to use Quantum Mechanics, now that you have mastered what is Quantum Mechanics in the first part. The topics to be covered include perturbation theories, variational principle, scattering, the WKB approximation, the adiabatic principle and the Berry's phase. These contents that you will learn will make you feel good, I believe, not only because you will learn to calculate things and apply your results to physical situations, but also because this process of using Quantum Mechanics will enrich your notion of what Quantum Mechanics really is all about.
