Graduate Bounded Packet Motion: Unravel the Asymptotically Helical Trajectory

[intervoxel]

In the article 'Cellular vacuum' (Int. J. Theor. Phys. 21: 537-551, 1982), Minsky writes: "One can prove that any bounded packet which moves within a regular lattice must have an asymptotically helical trajectory.. . " He does not explain this statement further, nor does he give any references.

I did not succeed in an internet search. I am intrigued by this feature, so I ask if anyone could help me in this regard, please.

Maybe he mentions Bloch's theorem https://en.wikipedia.org/wiki/Bloch's_theorem .

Can you provide the context of the statement perhaps. Not a journal I can access.
