Is anyone able to tell me if these patterns have been observed in lab experiments with plasma/z-pinches?

Yes, they have.
There are, to my knowledge, two avenues to pursue the spiral dynamic you've referenced in relation to plasma and electromagnetism/electric fields, electric currents etc. Its simply a matter of discerning, or deciphering under what nomenclature and/or perspective experimentalist refer to same:
1: One of my favorite sites in relation to this is "
Nonneutral Plasmas its conceptualization of "
vortex crystals." What I like about this approach is that the more diffuse "background" plasma are not neglected with regard to the formation of the "vortex crystals." This would seem to have direct relevance for the 'scavenging' or 'evacuation' (Thornhill) of the more diffuse "background" plasma electromagnetically 'compressed' or 'constricted' into the pinch region(s) whether as amorphous "
plasmoids" and/or totally tubular magnetic "field lines" and/or electric currents themselves.
Sorry for the run on sentence with that - and this:
So that when extrapolated, for example, unlike the disconnect or disjointed implications of say a "big bang physics' wherein the idea of a few millimeters sized hot dense quark-gloun filled chick-pea "singularity" supposedly existing within .... [insert speculative thing or condition here]? - the "background" plasma forms a necessary Continuum from which energetic 'self-organized' differentiations result in the formation of secondary energetic phase-states ('objects') that then
must co-exist within the same Continuum from which they are formed. Not disjointed and segmented at all no matter how large or diffuse the scale of the "background" plasma region (the "
molecular clouds" in space etc).
2: Also, seeming separate, other nomenclature from experimentalist with terms like "vorticity" in relation to the z-pinch dynamic can be Googled under that term i.e. z-pinch induced "
vorticity" and a bevy of relevant papers to boot.
Enjoy.
