Syllabus
Here you can find the lecture schedule, handouts, assignments, solutions, etc.
Contents
This is an advanced course in quantum mechanics, focusing on the applications of the basic theory and
practical methods introduced in QMI to optics, nuclear physics, particle physics, condensed matter physics, etc.
The main topics are:
Electromagnetic radiation
Scattering theory, Born series, partial wave analysis
Symmetry
Addition of angular momenta, WignerEckart theorem
Manyparticle systems and second quantization
Quantum entanglement
Prerequisites
PHGN 507: Electromagnetic Theory
PHGN 520: Quantum Mechanics I
Class Policies and Suggestions
I expect all students to attend every class. The statistics show that those seldom attend often get low scores.
If you have anything unclear, raise your hand and interrupt me immediately. You cannot afford
failing to understand any derivations or concepts. Do not let your confusion build up, go to my office and ask me;
otherwise you will get totally lost.
Ipads, laptops, cellphones, and other electronics are strictly forbidden during the class. Students
using these devices frequently in classes performed poorly.
Please go to my office often, not merely for homework problems.
I expect you to spend about 12 to 15 hours weekly to study the contents (57 hours) and finish homework (68 hours).
If you use a lot more than 15 hours per week, please let me know and I will try to help you out.
If you have any suggestions, concerns, worries, frustrations, etc, please let me know as soon as possible.
You may send me email, talk to me personally, or contact the class coordinator.
The class coordinator is responsible for contacting me immediately if she/he has any feedback from the class.
She/he will meet me in the middle of September, October, and November.


Homework Assignments
Homework will be assigned on every Tuesday (except for the test weeks), due on the next Wednesday at 2 PM.
Late due homework will get ZERO point, so just submit even incomplete.
But you can turn in homework late (up to 2 days before 5 PM Friday) twice during the semester without any reasons.
You need extraordinary reasons to get my permission to turn in late more than twice or two days each time.
You need to let me know 24 hours before the due time for any delay and get permission beyond the limit.
Totally there are about 12 assignments, and your lowest homework score will be dropped.
Clear and detailed derivations are crucial to get good scores.
It is totally fine to use Mathematica, but I encourage you to do derivations by hand.
I will try to inspect the graded homework as much as possible.
Go to my office to get homework grading errors corrected.
Academic Integrity
Homework assignments have to be done INDEPENDENTLY. Group discussions are encouraged
but you still need to finish the problems by yourself, and report it in your notes. If you use any materials from
papers, online resources, and books other than the textbook, please also report in your notes. No deduction will
be made if you report; otherwise I treat it as an academic integrity violation.
Exams and Quizzes
Two exams will be scheduled: a onehour midterm and a twohour final.
You will have three 20minute quizzes over the semester, with problems soly from homework assignments.
Quizzes are closedbook, with essential equations and formulae provided.
Exams are closedbook, but you can bring a piece of A4 paper with equations on one side.
If you have hard time memorizing an equation or formula, it means they will be given in the test if used.
Grading
Homework (50%) + Quizzes (3 × 4%) + Midterm Exam (14%) + Final Exam (24%)
A: ≥ 95%, A: 9094%; B+: 8789%, B: 8386%, B: 8082%
C+: 7779%, C: 7376%, C: 7072%; D: 6069%; F: 059%
In practice, the class is graded on a modified curve, so that the average is about 85% or better.
Any modifications will be only upwards, and be applied to everyone equally.
Specifically, the average of every exam (120 points each) and the sum of quizzes (30 points each) will be adjusted
at least equal to 80 by adding a same number to everyone. The homework average is expected to be over 80
(last semester is 87), so normally no adjustment is required.
If necessary, more points will be added to your total score until about 2/3 are B or better (including B, B+, A and A).
A: understanding the contents very well, excellent in both exams and homework assignemnts.
B: understanding the contents well, good in both exams, and homework is about the average.
C: understanding the contents poorly, exams are way below average, and homework is below average.
D: I won't normally give you a D. C is awful already. I give a D only if you seldom finish homework and
hardly work out any problems in the tests.
