Theoretical Description of Collective Excitations: Bloch Equations and Relaxation Mechanismstree Fock level leads to the semiconductor Bloch equations. Excitons are introduced as collective electron-hole excitations. The optical Stark effect and electron relaxation by phonon scattering are presented as application of the density matrix technique.
