Abstract: Abstract In Hartree-Fock calculations for atoms and molecules, multicenter-expansion methods are commonly used, especially those based on linear combinations of atomic orbitals (LCAO) using Gaussian-type orbitals (GTOs) or Slater-type orbitals (STOs). Artificial nodes, which are… read more here.

Published in 2021 at "Chemical Physics Letters"

DOI: 10.1016/j.cplett.2020.138285

Abstract: Abstract For each atom of a molecule, we introduce the structure unit group (SUG) consisted of the atom (called as core-atom) and the neighbor atoms. The kinds of SUG are sampled from small molecules, and… read more here.

Published in 2017 at "Physical Review A"

DOI: 10.1103/physreva.95.052504

Abstract: We present a general methodology to evaluate matrix elements of the effective core potentials (ECPs) within one-electron basis set of Slater-type orbitals (STOs). The scheme is based on translation of individual STO distributions in the… read more here.
