Course curriculum

1. Origin and properties of chemical bonds, modelling of crystal lattices.
2. Electrons in solids: free electron Fermi gas, periodic potential, band structure, electron density.
3. One-electron approximations, DFT – density functional theory, exchange-correlation functional.
4. Atomic sphere approximation, pseudopotentials for valence electrons, basis sets.
5. Dynamics of the crystal lattices, direct method (“frozen phonons”), linear response method.
