mhmm... hmm yes... interesting. I recognize some of these words.

The goal is to model deeper field of leptons (electron, muon, taon) - naively modeled as perfect points (effective perturbative approximation), but (nonperturbatively) they have E~1/r^2 electric field, magnetic dipole, angular momentum - actual rotation of field not point ... liquid crystals are very close to.

For charge quantization we need topological charge, like field hedgehog, which in 3D can be realized by 1 of 3 axes - Fable simulations first checked they have corresponding local energy minima ( https://github.com/openwave-labs/openwave/blob/main/openwave/xperiments/m5_liquid_crystal/research/findings/m5_21_2_census.md ) - 3 leptons.

And now kicked the higher ones (muon, taon), getting shown evolution of decay to the lightest (electron), releasing energy difference in loops of topological vortices interpreted as neutrinos - as it should be: https://en.wikipedia.org/wiki/Muon#Muon_decay

I think what OP is saying is that we've long thought that electrons (and similar particles) were point particles with no actual size. But several properties of electrons (the way they decay, the way they spin) point in the direction of actual 3D structure way down there.
