I would like to have Recitation 5 and 6 on Wednesday, like previous recitations, rather than on the day of Pset due, in case I have questions to address during recitation and TA office hours on Thursday :)

Response: This is a reasonable request, which it seems I can accommodate with my schedule. Assuming it does not conflict with other student priorites, I have tentatively modified the schudyle, with the new schedule here.

For Q3e Pset 2, should the question ask for recursion relations for (t, K_2, u) instead of K_sigma?
---
message sent anonymously
Response: Yes, but note the main issue is the recursion relations for (t,u).

Response: The Physics Homework bins are located at the intersection of buildings 8 and 16, on 3rd floor on building 8 (connecting to 4th floor of building 16). There is a box that is marked 8.334. If you prefer not to hand in paper copies, you can make arrangements with the TA (swmusserATmitDOTedu) to submit your work electronically.

To find the optimal BH_0 should we minimize the difference between <BH-BH_0> with respect to each m_alpha? Then do we use the self-consistency equations in e? And if so, is there a specific response function we should consider?

Response: The free energy, which is subject to the Gibbs inequality in part (d), has to be extremized with respect to the trial fields h.

For PSet1, Q4-(f), I assume the question intends the correction term to be \pi^2 / 3n^2 J_v, not \hat{J_v}? \hat{J_v} is dimensionless, so appearing alongside kT_c does not look correct.
---

Response: No, J is dimensionless \hat J has dimensions of k_BT.

For the remark immediately after Eqn (II.30) in lec3.dvi of https://web.mit.edu/8.334/www/lectures/lec4.html, could you slightly elaborate further? How did we obtain the first derivative of psi for Eqn (II.30)?

For the functional integral remark found in page 16 of the document Lec2.dvi, may you elaborate more (perhaps in class or over here)?
---

Response: For the top question I am confused as following II.30 there is no statement about derivatives. I believe these types of questions are best addressed, and discussions provided, in person (in class or after).

Are the response functions for a given system diverging a sufficient and necessary condition for a critical point?
---
message sent anonymously
Response: A diverging response is certainlhy indicztive of something interesting going on. I am relunctant to make a general statement that could require qualifications; e.g. transverse responses are infinite in an ordered phase when continuous symmetry is broken, due to Goldstone modes.
