Welcome to Phys 139B, 2012!

Please note that all course materials available from this web site are debugged and updated all the time. All changes are noted, just below the download link. Please make a habit of checking them semi-regularly. If changes are made due to observant students pointing out to me the need to make certain changes, then those students may get some benefit of getting a small "upward lift" at the end of the quarter. For instance, such changes were just made in LN 2. Basically, I record what I perceive as "good student deeds" in my "good deed file" (not only for debugging course materials but also for other things such as asking good questions, leading good discussions and helping other students) and will use it when students grades lie on borderline at the end of the quarter.
The inquiry to possibly get a new class room has been sent. I will keep you up to date, if anything develops. – I haven't heard anything about this yet, and my sense is that we will not have luck to get a new classroom. – 3:42PM, Oct 05, 2012

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.
