A pr 2 01 4 Correlation correction to configuration interaction singles from coupled cluster perturbation theory Jason
A new state specific correlation correction to configuration interaction singles (CIS) excitation energies is preseted using coupled cluster perturbation theory (CCPT). General expressions for CIS-CCPT are derived and expanded explicitly to first order in the wavefunction and second order in the energy. By virtue of the nature of CCPT this method is a priori size extensive and incorporates infi...
متن کاملAnalysis of Coupled Cluster and Quadratic Configuration Interaction Theory in Terms of Sixth-Order Perturbation Theory
The energy at sixth-order Mnller-Plesset (MP6) perturbation theory is given and dissected into 36 sizeconsistent energy contributions resulting from single ( S ) , double ( D), triple (T ), quadruple ( Q ) , pentuple (P), and hextuple (H) excitations. It is shown that MP6 is an O ( N 9 ) method, but less costly approximations to M P ~ are possible. M P ~ is used to analyze and compare coupled c...
متن کاملCoupled-cluster and configuration-interaction calculations for heavy nuclei.
We compare coupled-cluster (CC) and configuration-interaction (CI) results for (56)Ni obtained in the pf-shell basis, focusing on practical CC approximations that can be applied to systems with dozens or hundreds of correlated fermions. The weight of the reference state and the strength of correlation effects are controlled by the gap between the f(7/2) orbit and the f(5/2), p(3/2), p(1/2) orbi...
متن کاملLinear scaling multireference singles and doubles configuration interaction.
A linear scaling multireference singles and doubles configuration interaction (MRSDCI) method has been developed. By using localized bases to span the occupied and virtual subspace, local truncation schemes can be applied in tandem with integral screening to reduce the various bottlenecks in a MRSDCI calculation. Among these, the evaluation of electron repulsion integrals and their subsequent t...
متن کاملLocal correlation in the virtual space in multireference singles and doubles configuration interaction
We describe a multireference configuration interaction method that takes advantage of local correlation methods in both the internal ~originally occupied! and external ~originally unoccupied or virtual! orbital spaces. In the internal space, implementation of local correlation is trivial and involves neglecting configurations having simultaneous excitations out of widely separated orbitals. In ...
