One electron systems: Variational principle, trial wave-functions.



Two electron systems: Antisymmetry, Hartree-Fock and correlation.



Many electron systems: ground state and Hartree-Fock.



Density Functional Theory: Hohenberg-Kohn theorem and Thomas-Fermi.



Kohn-Sham equations: Exchange and correlations.



The Local Density Approximation: uniform electron gas.
