A density‐matrix many‐body theory for the description of the interacting electron–hole system in direct‐gap semiconductors is presented. The Coulomb interaction between all electrons, the coupling to a quantized light field, and a reservoir of phonons are included. The theory is evaluated to compute the electron–hole and electron–electron correlation functions after initialization of the system as uncorrelated plasma. The dynamical development of pair correlations is discussed.
