No, I was disagreeing with your claim that @Demystifier's posts are in disagreement with Norsen. They're not. Yes, and nothing I or...

No, they're not. Remember that in BM, the particle is just like a classical particle obeying an equation of motion--but the equation of...

This is not correct. The part of the pilot wave that appears in B's Hamiltonian always affects B. What is true is that the part of the...

He isn't. What he's emphasizing is that in BM, the wave function is not the state of the particle. The state of the particle is the...

But we can also say, knowing the result of the ##A## measurement, that only the portion of the ##B## pilot wave that is in the collapsed...

It doesn't have to. The pilot wave is just a part of the Hamiltonian that determines B's equation of motion. It doesn't have to "know"...

It's worth nothing, though, that when you use the words "before" and "after", as I understand it, those are relativistically invariant...

"Photon" is a limited term. That's why I said "quantum EM field" instead when I referred to the treatment in Ballentine. Only a very...

More precisely, that the 4-momentum wave vector of the light was set at emission. In terms of wavelength, that determines the wavelength...

That's not quite true. In quantum optics, for example, it's quite common to treat photons in an essentially non-relativistic way. See...

For details about spin in Bohmian mechanics I recommend https://arxiv.org/abs/1305.1280 For a relativistic version of Bohmian mechanics...

You're missing the point. In BM, the "value" of spin is not something separate from the particle's position. When we measure "spin" in...

No, it doesn't. It just has to act on the B particle in such a way as to ensure that it comes out of the proper arm of whatever...

Yes it does; "pilot wave" is just another name for the wave function. What BM has that orthodox QM does not have is the unobservable...

As I understand it, the simple answer to the title question, when does the pilot wave action cease? is never. The pilot wave is always...
