New publication by Simen Kvaal, Håkon Richard Fredheim, and Thomas Bondo Pedersen in collaboration with Mads Greisen Højlund at Aarhus University, Denmark. The paper is a study of the time-dependent bivariational principle (TD-BIVP), which is used to derive propagation schemes for many-electron systems, in particular time-dependent coupled-cluster theories. The authors also consider many popular coupled-cluster-based propagation schemes and place them into the context of the new analysis.
