PARADIGMS IN PHYSICS: PARADIGM 5
PH 425: Spin and Quantum Measurement
Winter 2001 (February 5  February 23)
Course Information
Course Goals:
 Understand and analyze sequential SternGerlach measurements
on spin systems
 Analyze generic quantum problem using matrix mechanics
 Use time evolution to understand spin precession
 Analyze generic time dependent quantum problem using matrix
mechanics
Course Work:
 Homework will be due each Friday.
 Practice problems will be assigned but neither collected nor
graded. In these problems, you will (1) practice using the tools
needed to do the homework, (2) derive properties that we will use
in class, and (3) solve variations of the four key problems
related to the course goals.
 Homework should be turned in before class on the day it is
due. The solutions will be posted promptly, after which homework
is considered late. If your homework is late, I may grade it if
you have an acceptable excuse, I may scale it as exp(N) where N
is the number of days past due.
 The ground rules for the homework are:
 1. We strongly encourage students to work with each other,
more advanced students, the TA, and the professor, when they
get stuck on assignments. However, each student is expected to
turn in independent assignments that show evidence of
individual thought.
 2. Homework solutions from previous years are strictly
offlimits. You are on your honor not to use them. Allow
faculty to use their time interacting with you, rather than
continually thinking up new assignments. Besides, if you don't
do the work yourself, it will show up very clearly on exams.
 3. Sources must be appropriately documented. If you find a
homework problem worked out somewhere (other than homework
solutions from previous years), you may certainly use that
resource, just make sure you reference it properly. If someone
else helps you solve a problem, reference that too. In a
research paper, the appropriate reference would be: Jane Doe,
(private communication).
