Resolving the notorious case of conical intersections for coupled cluster dynamics
Eirik F. Kjønstad, Henrik Koch
The motion of electrons and nuclei in photochemical events often involve conical intersections, degeneracies between electronic states. They serve as funnels for nuclear relaxation…

Crossing conditions in coupled cluster theory
Eirik F. Kjønstad, Rolf H. Myhre, Todd J. Martinez +1
We derive the crossing conditions at conical intersections between electronic states in coupled cluster theory, and show that if the coupled cluster Jacobian matrix is nondefective…
