Unformatted text preview: 3. Explicitly ll in the details of Exercise 3-3 (from the pages in your handout copied from the text by Goldenfeld), which sketches the derivation of the free energy of the nearest-neighbor Ising model in the mean eld approximation. 4. Develop a Landau expansion of the mean-eld 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 mean-eld critical exponents as the VDW uid produced. 5. Prepare solutions to the following problems in Chandler: 5.1, 5.2, 5.21, 6.3....
