Is the reason these are coherent quantum states that the postulated ultralight axions don't strongly interact with anything except gravity, so they see very little environmental noise to decohere them? Would they also predict there's (much smaller) dark matter halos around ordinary planets and stars, and these also have quantized atom-like states?
- wwarner 2y agoyes, just heard about it on Physics Frontiers. Monsalve & Kaiser are talking about primordial black holes, and are offering a theory that if they were imbalanced in color charge, they could be surrounded by a particle cloud, in a big quantum state. https://pca.st/episode/f0db6ab1-18ff-4201-a6b2-a30b780a266a https://pca.st/episode/f0db6ab1-18ff-4201-a6b2-a30b780a266a
