Smooth models for the Coulomb potential
Cristina E. González-Espinoza, Paul. W Ayers, Jacek Karwowski +1
Smooth model potentials with parameters selected to reproduce the spectrum of one-electron atoms are used to approximate the singular Coulomb potential. Even when the potentials do…
Spooky correlations and unusual van der Waals forces between gapless and near-gapless molecules
John F. Dobson, Andreas Savin, Janos G. Angyan +1
We consider the zero-temperature van der Waals interaction between two molecules, each of which has a zero or near-zero electronic gap between a groundstate and the first excited s…
Exchange-correlation functionals via local interpolation along the adiabatic connection
Stefan Vuckovic, Tom Irons, Andreas Savin +2
The construction of density-functional approximations is explored by modeling the adiabatic connection em locally, using energy densities defined in terms of the electrostatic pote…
