Week 9: Starred problems + helpful notes for Problem 4

Hi Folks:

  I am so sorry for posting a version of the reading/problems without any stars!  The version with stars is up;  due to hand in Wednesday are Problems 2, 4 and 7.

  Also,  Problem 4, G&T 5.18 requires you to have read about Mean Field theory in Section 5.7; and also grabbed the result of  the previous problem, which gives an improved expression for the free energy per spin: f(T,H). 

  You can certainly just grab that result, Eq. (5.126),  and go forward to solve G&T 5.18.  Still,  I've posted under "Resources" a couple of pages of notes that I hope lay a good foundation for understanding Mean Field theory, for that problem, and for seeing how critical exponents arise.

     Take care, 

       Amy
