prob 12 correction
I was told that the factor 2 in eq. 1 in prob 1, set 12, may not ne correct.
Do not trust it and find your own numerical factor!

Pset 1-12 grades and solutions
Dear all:All Pset 1-12 are graded and their solutions are posted. Please check your score to make sure that nothing is missing. You can pick up your pset write-up in class on Mon and Wed.
(1) the grades for pset 1 to 11 have the following scales:
pset 1: 30;
pset 2: 20;
pset 3: 40;
pset 4: 80;
pset 5: 50;
pset 6: 60;
pset 7: 70;
pset 8: 70;
pset 9: 100;
pset 10: 100;
pset 11: 100;
(2) Your grades can be read from the pset section. If you submit your pset online, you may receive some comments in the pset section.
(3) Many of you receive extra credits for the pset, because you (i) LaTex your pset solutions, or (ii) clearly explain the logic of your answers, or (iii) apply novel or creative methods solving the problems.
Best,
Juven

Superconductivity reading materials posted
Dear 8.511:Some reading materials about superconductivity are posted.
For 1st-year graduate students who have attended both Prof. Patrick Lee's Wed superconductivity lecture and the Prof. Wolfgang Ketterle's Tue lunch talk on Bose-Einstein condensation (BEC), you may find the similarity on the discussion of the physical reality of a gauge potential v.s. gauge invariance acting on the matter-field wavefunction. Some further interesting readings can be the notes shared below.
1. Superconductivity - Must read resource from chap 18 Grosso,
Parravicini's Solid State Physics:

This chap 18 is very useful for doing your Pset 12. You better read it first.
2. A short tutorial paper: Superconductivity using quantum field theory by Steven Weinberg:
3. Recitation 5 handout: https://stellar.mit.edu/S/course/8/fa14/8.511/courseMaterial/topics/topic1/studyMaterial/Recitation_Handout_5_Juven_Wang_superconduct/Recitation_Handout_5_Juven_Wang_superconduct.pdf
Enjoy.
Best Wishes,
Juven

8.511 Quiz: score is online and the solution is posted
Dear 8.511:Your quiz score shall be viewable online now. The test and the
solution is posted here:
https://stellar.mit.edu/S/course/8/fa14/8.511/homework/assignment10/
Please let me know if you cannot view your test score. On the
"Gradebook Module" of the Stellar page.
The score distribution for the class is here: https://stellar.mit.edu/S/course/8/fa14/8.511/courseMaterial/topics/topic1/exam/Preview_of_Gradebook_8.511_Quiz_distribution/Preview_of_Gradebook_8.511_Quiz_distribution.pdf
Mean 88.83.
Standard Deviation: 10.14
Total test takers: 49.
The max amount is 100+10=110. This extra 10 points for those who provide a 4 * 4 matrix solution for Prob 3 (a). The energy band gap will be 2U by solving the 4 * 4 matrix, while the 3 * 3 matrix provides a \sqrt{2} U gap, which strictly speaking is incorrect. However, both answers are accepted (due to the misleading statement of the problem).
The highest score of our test takers is 110. The lowest is still above 60.
Best,
Juven
