1. Feed back on Friday
2. Single particle states
3. Atom states are not independent, He with one electron in 2s, this energy varies if the other electron is in 1s or 3s.
4. Metals, doped semiconductors, independent model is OK.
5. Lev Landau and Fermi liquid theory: bit of history on Landau
6. Derive FD from grand partition function, make clear distinction between system states and single particle states.
7. No N!, states are distinguishable, by definition
8. Grand potential, N and U and S
9. Properties of FD distribution.

Trying to find out if students really got the occupation number idea. Not sure, expnanations seem OK, but written work not. Need in class test for that.

1. Review single particle states, system states
2. Review Gibbs factor, grand partition function, grand potential (no N!)
3. Review N and FD function, explain details of FD function
4. Get U and S
5. Introduce density of states
6. Approximate FD by piece-wise linear

• Have them try to get CV in piece wise linear approximation
