Droplets can also seem to “tunnel” through barriers, orbit each other in stable “bound states,” and exhibit properties analogous to quantum spin and electromagnetic attraction. When confined to circular areas called corrals, they form concentric rings analogous to the standing waves generated by electrons in quantum corrals.

Like an electron occupying fixed energy levels around a nucleus, the bouncing droplet adopted a discrete set of stable orbits around the magnet, each characterized by a set energy level and angular momentum.
Yes and yes and yes (those are all examples mentioned in the article). If you have a specific example of a quantum phenomenon that pilot wave theory doesn’t exhibit, I’d like to know. Pilot wave advocates claim that pilot wave theory results in the same predictions, although I haven’t had time to chase down sources or work this out for myself.
My knowledge of it is pretty superficial, but I’m pretty confused about how it represents states with a superposition of particle numbers. For fixed number of (non relativistic) particles you can always just put the interesting mechanics (including spin, electromagnetic charge, etc!) in the wavefunction and then add an epiphenomenal ontologically-fundamental-particle like a cherry on top. We’ll, epiphenomenal in the Von Neumann measurement paradigm, presumably advocates think it plays some role in measurement, but I’m still a bit vague on that.
Anyhow, for mixtures of particle numbers, I genuinely don’t know how a Bohmian is supposed to get anything intuitive or pseudo-classical.
So, does the bouncing oil droplet also tunnel through barriers, spontaneously arise or annihilate, and occupy discrete energy levels?
Because to me this seems like merely an analogy that works in some aspects, but fails in other aspects.
