Sci-hub doesn’t seem to have it, but Google shows the full paper mentions something about simulation. It looks like it’s only 8 oscillators and they actually built a physical implementation — why couldn’t this all have been done in simulation?

I think it would be fair to say that the entire purpose here is to determine exactly what it is we would need to understand and do to create an effective simulation. Hard to simulate when you're not sure what the relevant parameters are in the first place. (I say "hard" and not "impossible", because simulations can be a relevant part of working out what those parameters are, but speaking generally, that's something that you can do when you're already 90% of the way there, and it doesn't sound like we necessarily are.)

  Ah, thanks! PDF link: http://nano.caltech.edu/publications/papers/Matheny-2019-Science.pdf http://nano.caltech.edu/publications/papers/Matheny-2019-Sci... Looks like they did simulate it, and the experimental results differed from the simulation due to number of harmonic terms used: “To obtain quantitative agreement between the phase model (Eq. 3) and the experiment, additional terms in the harmonics of the magnitudes would need to be included in the phase model.” Which I suppose implies that very weak, distant harmonics might play an important role in these patterns. Also an earlier paper from the same group that discusses infeasibility of other approaches: https://authors.library.caltech.edu/81293/1/acs.nanolett.7b02026.pdf https://authors.library.caltech.edu/81293/1/acs.nanolett.7b0...
