- W2898921389 abstract "In the preceding Chap. 9, the algebraic–diagrammatic construction (adc) was established as a procedure to derive systematically higher-order approximations to the (varvec{M}^+(omega )) and (varvec{M}^-(omega )) parts of the dynamical self-energy (varvec{M}(omega )). The respective adc matrices could then be incorporated within a common Dyson secular matrix allowing one to solve the Dyson equation in the form of a hermitian eigenvalue problem. As a characteristic feature, the Dyson approach combines the ((N!-!1))- and ((N!+!1))-particle problems as parts of a common computational scheme. The adc procedure, however, is quite general and can be applied to the electron propagator as well, more precisely, to the (varvec{G}^-(omega )) or (varvec{G}^+(omega )) parts. Such a direct adc approach, described in this chapter, avoids the Dyson equation altogether and leads to separate adc schemes for the ((N!-!1))- and ((N!+!1))-particle problems. The obvious advantage of these direct or non-Dyson schemes is the smaller size of the secular problem, being roughly half the size of a comparable Dyson formulation. Moreover, the lowest ionization energies (or electron affinities) are at the edge of the eigenvalue spectrum (and not in the middle of the joint ((N pm 1))-particle energy spectrum). The price to be paid here is a higher complexity in the pt expansions of the secular matrix elements, which, however, is workable through the third-order adc(3) level." @default.
