Two modifications of the perturbative doubles correction to configuration interaction with
single substitutions (CIS (D)) are suggested, which are excited state analogues of ground …

A Laplace-transformed second-order Møller–Plesset perturbation theory (MP2) method is
presented, which allows to achieve linear scaling of the computational effort with molecular …

An improved algorithm is presented for the evaluation of the (T) correction as a part of our
local natural orbital (LNO) coupled-cluster singles and doubles with perturbative triples [LNO …

A new scheme for obtaining the approximate correlation energy in the divide-and-conquer
(DC) method of Yang [Phys. Rev. Lett. 66, 1438 (1991)] is presented. In this method, the …

This paper describes the extension of the linear-scaling divide-and-conquer (DC)-based
correlation method to the coupled cluster with singles and doubles excitations (CCSD) …

The divide‐and‐conquer (DC) method, which is one of the linear‐scaling methods avoiding
explicit diagonalization of the Fock matrix, has been applied mainly to pure density …

We implement the minimax approximation for the decomposition of energy denominators in
Laplace-transformed Møller–Plesset perturbation theories. The best approximation is …

It is shown that spin-component-scaled second order Møller-Plesset theory proposed by
Grimme [J. Chem. Phys. 118, 9095 (2003)] can be interpreted as a two-parameter scaling of …

A linear-scaling local second-order Møller–Plesset (MP2) method is presented for high-spin
open-shell molecules based on restricted open-shell (RO) reference functions. The open …

The authors have developed a fragmentation-based linear-scaling electronic structure
calculation strategy named the divide-and-conquer (DC) method, which has been …
