Greek 'anameixi' loosely means a mixture or a blending. The special states could be called 'anameixic', the property could be called 'anameixicity'.

Why am I trying to find a name for this? Otoh, why are so many physicists trying so hard to popularize their projects for the last 40 or 50 years? Oh .. I think I just answered my own question.

When it comes to using a regular computer to mimic (read: fake) the execution of an exotic program/API for nonexistnet future hardware, I highly recommend the humorously titled talk: "Temporally…

Is any of this experimentally testable in the real world?

Would gravity or spacetime under these definitions behave differently and yield something we can observe?

Or is this fancy math modeling that looks nice on paper, but that we won't be able to test until we become a Kardashev type III civilization?

Earlier quoted context omitted.

we had "god particle" too …

To be fair, that one came from an editor not a physicist; the physicist wanted to call their book «the goddamn particle», and it got censored/editorialized to «the god particle».

I've heard that story and it doesn't ring true to me. It's not that aggravating to find. Try measuring a neutrino mass, which is still an open problem and looks as if it will remain so for a very long time.

Calling something 'magic' is like an admission that you have no clue about what is going on. Seems to me, they do have some clue, namely that instead of codes with perfect isolation, there might be some advantage to studying ones that allow some blending. The resulting spaces may (or may not) lead to a better description of reality, but doing science means to peel back that mystery. So to go and promote this under th…

It sounds as if it's in the same vein that gave us "strange" and "charm" and "color" (in the strong force sense). There was a whimsical time in particle naming. I'd say it ended when they rejected "truth" and "beauty" in favor of "top" and "bottom".

We can do better than "magic".

Don't forget snap, crackle and pop, and quantum teleportation. Physicists get a failing grade for naming things.

You mean post quantum, theoretical physics. Up to 19th and early 20th, physicists somehow knew how to name things. It is possible that the nature of the beast itself has changed and it attracts a different kind of mindsets ...

Maybe it is easier to get funding with catchy and/or mysterious names?

IMHO, as an analogy, matter is not 'a bowling-ball on a mattress', but more like a scrunched-up section of table-cloth. Tiny knots or whirlpools of space-time/quantum fields, different particles are different topologies of knot, albeit the nature of space-time is unclear and it may well be a projection.

An ant traveling at constant speed on a "scrunched up section of a table cloth" will still take the same amount of time following the same path to get from A to B. Any material analogy requires some kind of stretching or compression.

Charm, quark, colors, time crystals, holographs.. And now, magic. Don't worry Einstein, no spooky action at a distance here, it's just magical. > The more non-Clifford gates you need to produce a quantum state, the more magical that state is. The group found that the particles were highly magical. ..They showed that magic gave space its springiness . Magic, in other words, is connected to space’s ability to bend. At…

You can just call it second stabilizer Rényi entropy or non-stabilizerness if you find "magic" strange and prose is more your flavor than poetry.

Strange quarks[1] are not magic. :)

I agree, the table-cloth is rubber.
