Development of algebraic techniques for the atomic open-shell MBPT(3)

R. Jursenas, G. Merkelis

The atomic third-order open-shell many-body perturbation theory is developed. Special attention is paid to the generation and algebraic analysis of terms of the wave operator and t…

Irreducible tensor form of three-particle operator for open-shell atoms

Rytis Jursenas, Gintaras Merkelis

The three-particle operator in a second quantized form is studied. The operator is transformed into irreducible tensor form. Possible coupling schemes, distinguished by the classes…
