You can have vacuum fluctuations without photons. EDIT: will try and find Compton paper later, going for walk now.

- defrost 3y agoLooking forward to your return, I'll be making popcorn :-) Nice to see a stand taken on uncommon ground.
- jpmattia 3y ago> You can have vacuum fluctuations without photons. Casimir is not about fluctuations. There is an attraction between metal plates in the absence of electromagnetic radiation. And as I think it through, an even simpler example is the laser. Bose-Einstein statistics require that you have indistinguishable particles to multiply occupy a state. Without the indistinguishability, you don't end up with the right statistics. Without the right statistics, you don't end up with the right Einstein rate equations, and you'll be missing the stimulated emission term. Without that term, you will be missing the lasing action, as well as secondary effects such as noise statistics.
