Abstract
In this chapter, we shall apply the second quantization formalism to a number of simple problems. To begin with, we consider a gas of noninteracting spin- ½ fermions for which we will obtain correlation functions and, subsequently, some properties of the electron gas that take into account the Coulomb interaction. Finally, a compact derivation of the Hartree–Fock equations for atoms will be presented.
