Welcome to Phys 139B, 2012!
Couple of corrections for problem 1 of homework – please check them!
You may notice that there are couple of challenge questions on the forum site. If you provide a good answer to a challenge question, then you will definitely be recorded in my good deeds file. Please regard challenge questions as "bounty hunter questions" or "extra credit questions."
Welcome to the second part of Quantum Mechanics!
In this course, you will learn how to use Quantum Mechanics, now that you have thoroughly learned, in 139A, what Quantum Mechanics is. (However, we will review the essentials of the formalism of Quantum Mechanics, as we begin 139B.) The topics to be covered include perturbation theories, the 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.
