Variational coupled cluster for ground and excited states
Antoine Marie, Fábris Kossoski, Pierre-François Loos
In single-reference coupled-cluster (CC) methods, one has to solve a set of non-linear polynomial equations in order to determine the so-called amplitudes which are then used to co…

Excited States From State Specific Orbital Optimized Pair Coupled Cluster
Fábris Kossoski, Antoine Marie, Anthony Scemama +2
The pair coupled cluster doubles (pCCD) method (where the excitation manifold is restricted to electron pairs) has a series of interesting features. Among others, it provides groun…
