Why doubly excited determinants govern configuration interaction calculations of electron correlations
Carlos L. Benavides-Riveros, José M. Gracia-Bondía, Michael Springborg
Computational evidence shows that, when using natural orbitals to study (dynamical and non-dynamical) electron correlation, determinants with an odd number of excitations play a ne…
Quasipinning and selection rules for excitations in atoms and molecules
Carlos L. Benavides-Riveros, Michael Springborg
Postulated by Pauli to explain the electronic structure of atoms and molecules, the exclusion principle establishes an upper bound of 1 for the fermionic natural occupation numbers…
Variational occupation numbers to a Müller-type pair-density
C. L. Benavides-Riveros, I. Nagy
Based on a parametric point-wise decomposition, a kind of isospectral deformation, of the exact one-particle probability density of an externally confined, analytically solvable in…
