Before revision:  In  a recent study  , it was proposed to  consider simulations as made of dozens of sequences of eigenvalue problems , where each sequence groups together eigenproblems with equal {\bf k}-vectors and an increasing outer-iteration cycle index i. It was then demonstrated that successive eigenproblems in a sequence are strongly correlated to one another.
After revision:  In a recent study , it was proposed to consider simulations as made of dozens of sequences of eigenvalue problems , where each sequence groups together eigenproblems with equal {\bf k}-vectors and an increasing outer-iteration cycle index \ell. From this different standpoint it was possible to demonstrate that, contrary to belief, successive eigenproblems in a sequence are strongly correlated to one another.
