Localized versus extended systems in density-functional theory: some lessons from the Kohn-Sham exact exchange potential
C. M. Horowitz, C. R. Proetto, J. M. Pitarke
A long-standing puzzle in density-functional theory is the issue of the long-range behavior of the Kohn-Sham exchange-correlation potential at metal surfaces. As an important step…

Benchmark Quantum Monte Carlo calculations of the ground-state kinetic, interaction, and total energy of the three-dimensional electron gas
I. G. Gurtubay, R. Gaudoin, J. M. Pitarke
We report variational and diffusion Quantum Monte Carlo ground-state energies of the three-dimensional electron gas using a model periodic Coulomb interaction and backflow correcti…
