Interpretation of Coupled-Cluster Many-Electron Dynamics in Terms of Stationary States
Thomas Bondo Pedersen, Håkon Emil Kristiansen, Tilmann Bodenstein +2
We demonstrate theoretically and numerically that laser-driven many-electron dynamics, as described by bivariational time-dependent coupled-cluster theory, may be analyzed in terms…

A state-specific multireference coupled-cluster method based on the bivariational principle
Tilmann Bodenstein, Simen Kvaal
A state-specific multireference coupled-cluster method based on Arponen's bivariational principle is presented, the bivar-MRCC method. The method is based on singlereference theory…

Guaranteed convergence for a class of coupled-cluster methods based on Arponen's extended theory
Simen Kvaal, Andre Laestadius, Tilmann Bodenstein
A wide class of coupled-cluster methods is introduced, based on Arponen's extended coupled-cluster theory. This class of methods is formulated in terms of a coordinate transformati…
