Gradient expansions for the large-coupling strength limit of the Møller-Plesset adiabatic connection
Timothy J. Daas, Derk P. Kooi, Arthur J. A. F. Grooteman +2
The adiabatic connection that has as weak-interaction expansion the Møller-Plesset perturbation series has been recently shown to have a large coupling-strength expansion in terms…
Variations of the Hartree-Fock fractional-spin error for one electron
Hugh G. A. Burton, Clotilde Marut, Timothy J. Daas +2
Fractional-spin errors are inherent in all current approximate density functionals, including Hartree-Fock theory, and their origin has been related to strong static correlation ef…
Noncovalent interactions from models for the Møller-Plesset adiabatic connection
Timothy J. Daas, Eduardo Fabiano, Fabio Della Sala +2
Given the omnipresence of non-covalent interactions (NCIs), their accurate simulations are of crucial importance across various scientific disciplines. Here we construct accurate m…
