Detailed description of subjects covered in QMII 2007
Use materials from La Bellac (La) and from Merzbacher (Mer)
1. Symmetry in QM: La 8.1, 8.2, 8.3.
2. Angular momentum and tensor operator : La 10.1, 10.2, 10.3, 10.4 (supplemental materials on appications were added)
3. Scattering Theory: from La Bellac, Merzbacher, Schiff
(potential scattering, partial wave expansion, resonances, scattering length, integral equation, Green function, Coulomb problem)
4. Idential particles: from La Bellac, Schiff (spin statistics, scattering of identical particles)
5. The harmonic oscillator and field quantization : La Bellac
(N-representation, quantization of EM fields; vacuum fluctuations)

Homework assignment -- procedure and rules
1. A new set will be given for each chapter and will be posted on the web. The due date for each set will be announced through e-mails.
2. I will take a quick look at each homework returned. I encourage students to work together. I would ask the formation of groups, each group consists of three or four students. Still each student writes her/his own report.
3. For each homework assignment, you will get 25 points for attempting all of them. Partial efforts will get partial credits.
4. Each time, I will choose reports from four students at random for more careful grading. Additional points will be added to these students if the report is well done. The maximum additional points will be 10 for each paper I read. Weaker students have more chances to be selected for this category.
5. Each week I will select one or more students to prepare the "solutions" of the given problems, rewritten in a "neat" form which will then be posted on the web. Each posting will "earn" you ten points and your name will appear on the solution.
6. If you get 25 points from each homework assigned, at the end of the semester the grade for the homework portion will be 25 points. The additional points you "earned" will be the bonus. Thus if we have ten assignments and you get 250 points at the end of the semester your homework grade will be 25. If you get 100 points of bonus plus the 250 points, your homework grade will be 25x350/250=35 points.
Summary and Reviews
1. Reserve Wednesdays late afternoon 5:00-6:30pm for this class. The time will be used for make-up lectures or for help sessions.
2. At the end of each chapter there will be a short summary.
Students are encouraged to send e-mails or visit with me for suggestions for improving your learning experience.
Students with disabilities: If you have any condition such as a physical or learning disability, which will make it difficult for you to carry out the work as I have outlined it or which will require academic accommodations, please notify me and contact the Disabled Students Office (Holton 202), in the first two weeks of the course
Plagiarism: Plagiarism and cheating are serious offenses and may be punished by failure on the exam, paper or project; failure in the course; and/or expulsion from the University.
