TEXT:
We will follow Prof. Cheng's Physics 215A recommendation of
"Modern Quantum Mechanics," by J. J. Sakurai,
Revised Edition, and "Principles of Quantum Mechanics," by R. Shankar,
2nd Edition. As with 215A,
we will not follow exactly the order
of these books but much of the emphasis will be similar.
DISCUSSION LEADER: Kara Farnsworth

OFFICE HOURS: Wednesday 1:00-2:00 pm.
SYLLABUS:
This is a continuation of the first year graduate sequence in quantum
mechanics. One of our goals will be to introduce some modern quantum
mechanics problems in addition to the more
foundational `historic' material.
We will begin by reviewing and building
on material from Physics 215A:
*
Heisenberg Hamiltonian
(illustrates addition of angular momentum, matrix picture of QM, and
introduces an important model in quantum magnetism)
*
Entanglement entropy (an application of density matrices and
introduces a new tool to explore "quantum phase transitions")
*
path integral for harmonic oscillator
in "imaginary time"
(builds on intro given in 215A, emphasizes connection to
statistical mechanics).
and then turn to new material, covering:
*
Hydrogen atom
*
Time independent perturbation theory
*
"Tight Binding" Hamiltonians
(another illustration of matrix picture of quantum mechanics,
central model of energy bands in solids)
*
Time dependent perturbation theory
*
Scattering theory.

SOME PROBLEM SETS AND EXAMS FROM A PAST 215B COURSE I TAUGHT.
It has been quite a while since I taught 215B, these are the assignments
I managed to find.
We will not follow these very closely, but they are a guide to some
of the material we will cover.
