WebOct 1, 2024 · The Chachiyo formula [8] is an elegant m odel for representi ng the correlation energy of the uniform electron gas with a n economic paramete r set. By using the lea st squares fit, Eq. 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… WebJul 31, 2024 · A non-empirical exchange functional based on an interpolation between two limits of electron density, slowly varying limit and asymptotic limit, is proposed.
