General correlated geminal ansatz for electronic structure calculations: exploiting Pfaffians in place of determinants
Claudio Genovese, Tomonori Shirakawa, Kousuke Nakano +1
We propose here a single Pfaffian correlated variational ansatz, that dramatically improves the accuracy with respect to the single determinant one, while remaining at a similar co…
The nature of the chemical bond in the dicarbon molecule
Claudio Genovese, Sandro Sorella
The molecular dissociation energy has often been explained and discussed in terms of singlet bonds, formed by bounded pairs of valence electrons. In this work we use a highly corre…
Assessing the Accuracy of the Jastrow Antisymmetrized Geminal Power in the H4 Model System
Claudio Genovese, Antonella Meninno, Sandro Sorella
We report a quantum Monte Carlo (QMC) study, on a very simple but nevertheless very instructive model system of four hydrogen atoms, recently proposed in Ref. 1. We find that the J…
