Quantum Mechanics II
Time and Location
Tuesday, 4:30 pm-7:10 pm, 01/22-05/15, Robinson Hall B105
Tuesday and Thursday 2:00-3:00 pm or by appointment, Planetary Hall, Rm 207
For the sake of continuity, I will continue to follow (only loosely) the book
Modern Quantum Mechanics, 2nd Edition, J. J. Sakurai, and J. J. Napolitano
and cover chapter 5 to 7. Plenty of materials from other sources will also be used.
Typos are abound in the book, proceed with caution.
Homework (50%) + Midterm (25%) + Final exam (25%)
There will be 8 (or less) sets of homeworks. Late homework will not be accepted. Homeworks are graded on a coarse level: Excellent (5), Very Good (4), Fair (3), Absent (0).
Both exams will be open book, take-home.
Prerequisites & Course Goals
This course continues from Phys 684, Quantum Mechanics I (chapter 1 to 4 of Sakurai). We will apply the principles you learned from 684 to solve important problems found in AMO, condensed matter, and nuclear/particle physics. Most of these problems cannot be solved exactly, so we will focus on the art of approximations. Each approximation method will be illustrated by working out examples in detail. We will also develop concepts and techniques to treat many-body quantum systems. Time permitting, we will take a peek at quantum electrodynamics in its simple form (two-level atoms interacting with photons).
1. Semiclassical expansion [done]
