Optimized pair natural orbitals for the coupled cluster methods
Marjory C. Clement, Jinmei Zhang, Cannada A. Lewis +2
We present the coupled-cluster singles and doubles method formulated in terms of truncated pair-natural orbitals (PNO) that are optimized to minimize the effect of truncation. Comp…

Exploration of Reduced Scaling Formulation of Equation of Motion Coupled-Cluster Singles and Doubles Based on State-Averaged Pair Natural Orbitals
Chong Peng, Marjory C. Clement, Edward F. Valeev
A reduced-complexity variant of equation-of-motion coupled-cluster singles and doubles (EOM-CCSD) method is formulated in terms of state-averaged excited state pair natural orbital…
