I would say classical wave (equations) are about propagation. One can distinguish between propagation in time, and propagation along a ray in space. The group velocity is typically closer associated to propagation in time, while the phase velocity is closer associated to propagation along a ray...

Do you have a reference for Zurek? I know that he talks about envariance, but I would like to read where he talks about large numbers of worlds.

Allowing Cross-Site Tracking didn‘t help. But associating a standard password with the account email did work.

I will test this tonight. It looks to me like my issue should be solvable on my side, without action from Greg Bernhardt. I will report back the results.

Because conceptually, you have a wavefunction of a single electron (or rather a statistical collection of them) at the surface of the detector, which stays the same, independent of whether you use a normal detector screen or a plastic detector screen. And if you take the modulus squared of that...

People working on the theoretical side of electron microscopy and charge particle optics know how to compute such scenarios. The question is, how did they learn those fundamentals, and how do they refers to them in their papers. Here is how a Ph.D. dissertation I consulted while working on...

My prediction is that the starting positions of the tracks will show the same interference pattern as the normal detector screen. And in such a setup, the angular resolution provided by the tracks will be insufficient to determine through which slit the particle went. (Because the slit is...

It doesn't work with an iPad Air M2 either. Not with Safari, not with Chrome, and not with Firefox.

I thought the intention was to have an experiment where interference can be observed, like for example in...

But then the interference pattern becomes much too fine to be resolved:

Should have been D ≫ w. I fixed it.

My "actual math" rather tells me that "the slits have a finite separation that is small compared to the wavelength of the momentum states involved". Good. Let me parameterize the relevant geometric situation as follows λ: wavelength of proton D: distance between the slits plane and the plastic...

We all agree that the plastic is not at the slits, but at the screen. So in this scenario, any "supposed" measurement of the position at the slits is a retrodiction. Good, if you really measure the momentum accurate enough such that the angular resolution allows you to determine which slit the...

No, retrodiction is neither bound by uncertainty relations (think about the EPR paper), nor does it necessarily destroy interference. A track of the proton in the plastic can reveal information about its momentum. But because the of the uncertainty relation between position and momentum...

If you want, you can contact Arnold Neumaier. He recently embraced a research program (basically because TomS triggered discussions which triggered him to explain some related stuff in more detail) with similar "beables" and similar goals...
