32. The observation of Shubnikov–de Haas oscillations also requires that the splitting between Landau levels be larger than their width.
33. We note that this condensation does not by itself produce any change in resistivity, since the Drude formula gives the same value of conductivity for classical (Boltzmann) and quantum (Fermi) statistics, nor does it explain the anomalous effects observed in response to magnetic field (Ref. 2) in the “quantum” state.
34. We have assumed that the effective mass is not increased by electron-electron interactions that would lead to even smaller (Formula presented) We also note that (Formula presented) changes in a magnetic field and increases up to (Formula presented) when all the electrons are fully spin polarized.
