There are all sorts of &quot;particles&quot; that exist in solid matter such as https://en.wikipedia.org/wiki/Exciton https://en.wikipedia.org/wiki/Cooper_pair which are really about a few (or a huge number of) particles behaving collectively like one particle. Things like that happen in particle physics too (e.g. a proton is not an elementary particle but the quarks that make it up are, the whole situation by which particles get their masses from the Higgs Boson involves some interacting particles and fields finding an eigenstate that doesn&#x27;t interact, etc.) But then…</p><p><a href="https://hackerpaper.kaipfister.de/p/1409.6550/">Paper and discussion history</a>.
