Explicitly correlated formalism for second-order single-particle Green's function (1708.06474v1)
Published 22 Aug 2017 in physics.chem-ph
Abstract: We present an explicitly correlated formalism for the second-order single-particle Green's function method (GF2-F12) that does not assume the popular diagonal approximation, and describes the energy dependence of the explicitly correlated terms. For small and medium organic molecules the basis set errors of ionization potentials of GF2-F12 are radically improved relative to GF2: the performance of GF2-F12/aug- cc-pVDZ is better than that of GF2/aug-cc-pVQZ, at a significantly lower cost.
