Uniform electron gases. III. Low-density gases on three-dimensional spheres

Agboola, Davids (Adetomiwa); Knol, Anneke; Gill, Peter; Loos, Pierre-Francois


By combining variational Monte Carlo (VMC) and complete-basis-set limit Hartree-Fock (HF) calculations, we have obtained near-exact correlation energies for low-density same-spin electrons on a three-dimensional sphere (3-sphere), i.e., the surface of a four-dimensional ball. In the VMC calculations, we compare the efficacies of two types of one-electron basis functions for these strongly correlated systems and analyze the energy convergence with respect to the quality of the Jastrow factor....[Show more]
