Unformatted text preview: 3. Explicitly ll in the details of Exercise 33 (from the pages in your handout copied from the text by Goldenfeld), which sketches the derivation of the free energy of the nearestneighbor Ising model in the mean eld approximation. 4. Develop a Landau expansion of the meaneld free energy per spin for the Ising model (with coordination number z ) in powers of the average magnetization to O( 4 ). Show that this leads to the same classical or meaneld critical exponents as the VDW uid produced. 5. Prepare solutions to the following problems in Chandler: 5.1, 5.2, 5.21, 6.3....
