The Spin of the Electron,c limit deriving the Pauli equation. This Pauli equation, which is nothing else than the Schrödinger equation with an additional term containing the spin operator, predicts very accurately the magnetic moment of the electron. Finally, we discuss the relativistic hydrogen atom and the fine-structure corrections to the non relativistic one.

Many-Body Systems,lso the density functional theory, historically introduced by Thomas and Fermi to model the electronic cloud of atoms and recently applied also to atomic Bose-Einstein condensates. Finally, we illustrate the Born-Oppenheimer approximation, which is very useful to treat molecules composed by many electrons in interaction with several nuclei.

Second Quantization of Matter,ield can be expressed as a infinite sum of harmonic oscillators. These oscillators, which describe the possible eigenfrequencies of the matter field, are quantized by introducing creation and annihilation operators acting on the Fock space of number representation.
