You need to be specific on what kind of phase you're talking about. Like @PeterDonis said: A single pure state has no physical absolute...

There are classical mechanical formalisms based on Hilbert spaces like this: Koopman–von Neumann classical mechanics.

Not in the usual formulation of non-relativistic QM, where a "quantum state" is a ray in Hilbert space, not a vector. Multiplying a...

If you are making 2-D drawings, why do you need 3-axis motor movement? If you need to just lift the pen in the 3rd dimension, you can...

It would all make more sense if whole milk was just called 3% milk or something.

Hardware recommendations are here: Hardware Recs. Basically any integrated graphics chip that supports WebGL 2.0 will work. You...

Quite apart from the particular case of a laser, this is wrong. As a counterexample, the electron gun inside a cathode ray tube emits...

No, when a quantum particle is confined to the ##x y## plane, its Hilbert space is restricted, and there aren't even any such operators...

To illustrate what a la-la land the current grading practice at Harvard inhabits, the Harvard college student handbook already defines...

Grade inflation is a problem everywhere : https://www.gradeinflation.com/ Personally, I think it's detrimental for students sense of...

Don't post any Zenodo links. If you get it published you can post and discuss.

Have you considered simply trying to "run it up the flagpole"? In other words: write a clear paper, send it to the appropriate journal...

Huh, this is just untrue. Works are published and peer reviewed to add to the body of human knowledge. Also, arxiv is a repository, not...

That's not what the forum is for.

When you let AI write your question for you it just becomes muddy about what you're actually trying to ask or what you really understand.
