Abstract: The in-medium behavior of the nucleon spectral density includingself-energies is revisited within the framework of QCD sum rules. Specialemphasis is given to the density dependence of four-quark condensates. Acomplete catalog of four-quark condensates is presented and relations amongthem are derived. Generic differences of such four-quark condensates occurringin QCD sum rules for light baryons and light vector mesons are discussed.
