Molecular electronic structure in one-dimensional Coulomb systems

Caleb J. Ball, Pierre-François Loos, P. M. W. Gill

Following two recent papers [Phys. Chem. Chem. Phys. 2015, \textbf{17}, 3196; Mol. Phys. 2015, \textbf{113}, 1843], we perform a larger-scale study of chemical structure in one dim…

Many-electron integrals over gaussian basis functions. I. Recurrence relations for three-electron integrals

Giuseppe M. J. Barca, Pierre-François Loos, Peter M. W. Gill

Explicitly-correlated F12 methods are becoming the first choice for high-accuracy molecular orbital calculations, and can often achieve chemical accuracy with relatively small gaus…

The uniform electron gas

Pierre-François Loos, Peter M. W. Gill

The uniform electron gas or UEG (also known as jellium) is one of the most fundamental models in condensed-matter physics and the cornerstone of the most popular approximation ---…

Three-electron coalescence points in two and three dimensions

Pierre-François Loos, Nathaniel J. Bloomfield, Peter M. W. Gill

The form of the wave function at three-electron coalescence points is examined for several spin states using an alternative method to the usual Fock expansion. We find that, in two…

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

Davids Agboola, Anneke L. Knol, Peter M. W. Gill +1

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 e…

Basis functions for electronic structure calculations on spheres

Peter M. W. Gill, Pierre-François Loos, Davids Agboola

We introduce a new basis function (the spherical gaussian) for electronic structure calculations on spheres of any dimension . We find \alert{general} expressions for the one- a…
