Outline of the minicourse

  1. Degenerate Fermi gas: particle distribution function, Fermi energy, Fermi momentum, excitations.
  2. Thermodynamics of the Fermi gas.
  3. Interaction in Fermi gases. Repulsive weakly interacting two-component Fermi gas (normal Fermi gas). Basics of the Landau Fermi-liquid theory. Landau zero sound.
  4. Two-component Fermi gas with an attractive interaction. Cooper instability.
  5. BCS Hamiltonian and Bogoliubov transformation. Critical temperature. Single-particle excitations. Gap equation. Thermodynamics.
  6. Comparison between normal and superfluid Fermi gases.
  7. Effective Landau-Ginzburg description. Josephson current. Vortices. Andreev reflection.
  8. Collective modes (Bogoliubov sound).
  9. Ideas of Migdal-Eliashberg theory.
