Singular constant control trajectories and transition degeneracies in a closed 4-level quantum system

We analyze in this paper controllability aspects for a 4-dimensional quantum system. The "strong regularity" (cf. [1]) has been proven to be sufficient condition for global controllability. A conjecture in the literature asks whether this
