Chachiyo formula
WebJul 31, 2024 · While preparing the manuscript, the exchange functional has drawn interest from a few authors. It was implemented in the LibXC under the name “Chachiyo exchange”. It was also used to compute atomic potentials for a new initial guess method called SAP (Superposition of Atomic Potential). The study used 259 test molecules and reported that ... Local-density approximations (LDA) are a class of approximations to the exchange–correlation (XC) energy functional in density functional theory (DFT) that depend solely upon the value of the electronic density at each point in space (and not, for example, derivatives of the density or the Kohn–Sham orbitals). Many approaches can yield local approximations to the XC energy. However, overwhelmingly successful local approximations are those that have been derived fro…
