Solid State Physics Homework

• Homework #1 (due Wednesday, Feb. 10) Simon, problem #3.1 (Drude model, static and dynamic), 4.1a-c (Fermiology). For 3.1e take E//x and only calculate sigma_xx.
• Homework #2 (due Wednesday, Feb. 17) Simon, problem #4.2 (Electron velocities), 4.7 (Electron gas bulk modulus)
• Homework #3 (due Wednesday, Feb. 24) Simon, problem #19.7 (note the energy levels for spin-J are E_m=g*mu*B*m, with m ranging from -J to +J in integer steps). Electron gas magnetic susceptibility.
• Homework #4 (due Wednesday, March 3) Landau levels, Sound speed in water, Simon #9.1 (classical and quantum vibrations).
• Homework #5 (due Wednesday, March 10) Simon 2.2b (Debye heat capacity of potassium iodide), 2.3 (Debye model in 2D).
• Homework #6 (due Wednesday, March 17) Superconducting critical field
• Homework #7 (due Wednesday, March 24) Simon 9.2b-f (normal modes), 9.4 (decaying waves)
• Homework #8 (due Wednesday, March 31) Simon 11.4a (two orbitals/atom, note "diatomic" should read "divalent"), 11.5a (impurity state)
• Homework #9 (due Friday, April 9) Simon 23.1 (Itinerant ferromagnetism, long). Compare the 5/3 power law with your result in problem 4.7a.
• Homework #10 (due Monday, April 19) Simon 13.1 (reciprocals to BCC and FCC lattices), 13.3 (lattice plane direction and spacing).
• Homework #11 (due Friday, April 30) 14.3 (extinctions in x-ray diffraction), 14.4 (neutron diffraction), 15.4 (Square lattice, nearly free electrons). Note: the vectors labeled G in the statement of the problem should instead be labeled k.
• Homework #12 (due Friday, May 7) Simon 16.2 (2D Fermi surfaces in tight binding approximation), 17.4 (electron energy density, note this is in the conduction band), 18.4 (heterojunction electron gas, note the problem should state Ec2 < Ec1). Please fill out your FCE for this course.
