Correlated Transitions of Bloch Electrons

In solid-state physics, it is the Coulomb interaction which keeps the world together. In the last chapter the Coulomb interaction entered merely implicitly, owing to the occurrence of effective rather than free particle masses. However, not only are the correct one-particle energies determined by interaction effects, but also the optically excited electrons in the conduction band and the holes left in the valence band are influenced by their mutual interaction. To neglect these interactions is a serious omission, which will be remedied in this and the following chapter to the lowest level of approximation.
