Local and global interpolations along the adiabatic connection of DFT: a study at different correlation regimes
Local and global interpolations along the adiabatic connection of DFT: a study at different correlation regimes
Interpolating the exchange-correlation energy along the density-fixed adiabatic connection of density functional theory is a promising way to build approximations that are not biased towards the weakly correlated regime. These interpolations can be done at the global (integrated over all spaces) or at the local level, using energy densities. Many …
