Beschreibungen/Notizen

• A new diagram technique developed for strongly correlated electron systems is used to investigate the properties of the Anderson periodic model in the superconducting state. For the consistent description of both normal and anomalous Green's functions, an additional charge quantum number is introduced which discriminates between electron generation and electron annihilation operators. Dyson equations are derived for the Green's functions of zone and localized electrons in the case of superconductivity. The equations obtained here allow for the existence of both singlet and triplet superconductivity. (AIAA)
