The CO-ADC program suite has been designed to calculate band structures of semiconducting and insulating crystals. Thereby, the electron correlations are accounted for on ab initio level using the crystal orbital algebraic diagrammatic construction (CO-ADC) scheme. The theory is described in detail in the dissertation of Christian Buth and the related paper of C. Buth, U. Birkenheuer, M. Albrecht, P. Fulde Phys. Rev. B 72, 195107 (2005) which is also available via arXiv:cond-mat/0409078.
The CO-ADC scheme is based on the algebraic diagrammatic construction (ADC) scheme for atoms, molecules, and clusters developed by the Theoretical Chemistry of the Ruprecht-Karls-Universität Heidelberg, Heidelberg, Germany. Please consult the articles of J. Schirmer, Phys. Rev. A 26, 2395-2416 (1982) and J. Schirmer, L. S. Cederbaum, O. Walter, Phys. Rev. A 28, 1237-1259 (1983) for details.
The present implementation of CO-ADC is based on the WANNIER program described in A. Shukla, M. Dolg, H. Stoll, P. Fulde, Chem. Phys. Lett. 262, 213--218 (1996) and in C. Buth, Phys. Rev. B 75, 125121 (2007).
