@HF and BSE methods in periodic systems from Hartree-Fock theory: gaussian orbital and density fitting approach
Charles H. Patterson
The method for calculating quasi-particle energies of solids commonly begin from a DFT Hamiltonian and Kohn-Sham orbitals in a plane wave basis. Screening of the coulomb inter…
Positron annihilation and binding in aromatic and other ring molecules
E. Arthur-Baidoo, J. R. Danielson, C. M. Surko +6
Annihilation spectra are presented for aromatic and heterocyclic ring molecules resolved as a function of incident positron energy using a trap-based positron beam. Comparisons wit…
Gaussian-basis many-body theory calculations of positron binding to negative ions and atoms
J. Hofierka, B. Cunningham, C. M. Rawlins +2
Positron binding energies in the negative ions H, F, Cl and Br, and the closed-shell atoms Be, Mg, Zn and Ca, are calculated via a many-body theory approach develop…
Many-Body Theory Calculations of Positron Scattering and Annihilation in H, N and CH
C. M. Rawlins, J. Hofierka, B. Cunningham +2
The recently developed ab initio many-body theory of positron molecule binding [J. Hofierka et al., Nature, 606, 688 (2022)] is combined with the shifted pseudostates method [A. R.…
