In an attempt to find the (actual) OACCD ground state, we can try to implement an imaginary time-propagation scheme for the already existing time-dependent solvers. This would benefit from the change of convention of the time-dependent solvers as proposed by @halvarsu.

Good idea! We'll have a look at your implementation @rolfheil!

There is a discussion of imaginary time propagation for time-dependent vibrational coupled-cluster (same underlying amplitude equations) in section H of this article: https://aip.scitation.org/doi/10.1063/1.5117207
