Variational determination of the second-order density matrix for the isoelectronic series of beryllium, neon and silicon
Brecht Verstichel, Helen van Aggelen, Dimitri Van Neck +2
The isoelectronic series of Be, Ne and Si are investigated using a variational determination of the second-order density matrix. A semidefinite program was developed that exploits…

Quasiparticle properties in a density functional framework
D. Van Neck, S. Verdonck, G. Bonny +2
We propose a framework to construct the ground-state energy and density matrix of an N-electron system by solving selfconsistently a set of single-particle equations. The method ca…
