CC2 oscillator strengths within the local framework for calculating excitation energies (LoFEx)
Pablo Baudin, Thomas Kjærgaard, Kasper Kristensen
In a recent work [Baudin and Kristensen, J. Chem. Phys. 144, 224106 (2016)], we introduced a local framework for calculating excitation energies (LoFEx), based on second-order appr…
Convergence of coupled cluster perturbation theory
Janus Juul Eriksen, Kasper Kristensen, Devin A. Matthews +2
The convergence of a recently proposed coupled cluster (CC) family of perturbation series [Eriksen, J. J. et al., J. Chem. Phys. 140, 064108 (2014)], in which the energetic differe…
A view on coupled cluster perturbation theory using a bivariational Lagrangian formulation
Kasper Kristensen, Janus Juul Eriksen, Devin A. Matthews +2
We consider two distinct coupled cluster (CC) perturbation series that both expand the difference between the energies of the CCSD (CC with single and double excitations) and CCSDT…
