A note on recursive calculations of particular 9j coefficients
Jean-Christophe Pain
The calculation of angular-momentum coupling transformation matrices can be very time consuming and alternative methods, even if they apply only in special cases, are helpful. We p…
Koopmans' theorem in statistical Hartree-Fock theory
Jean-Christophe Pain
In this short paper, the validity of Koopmans' theorem in the Hartree-Fock theory at non-zero temperature (Hartree-Fock statistical theory) is investigated. It is shown that Koopma…
Generating functions for canonical systems of fermions
Jean-Christophe Pain, Franck Gilleron, Quentin Porcherot
The method proposed by Pratt to derive recursion relations for systems of degenerate fermions [Phys. Rev. Lett. 84, 4255 (2000), arXiv:nucl-th/9905055] relies on diagrammatic techn…
A consistent approach for mixed detailed and statistical calculation of opacities in hot plasmas
Quentin Porcherot, Jean-Christophe Pain, Franck Gilleron +1
Absorption and emission spectra of plasmas with multicharged-ions contain transition arrays with a huge number of coalescent electric-dipole (E1) lines, which are well suited for t…
