If the electron is orbiting the neutron in a hydrogren atom, then certainly it experiences acceleration. But accelerating charges emit photons. Where is the photon?

Why is it always 1912? I hate this stupid time machine.

except it doesn’t. And it’s the proton, not the neutron.

The electron doesn't orbit the proton. The electron's wavefunction stays stationary around the hydrogen nucleus. This is because the wavefunction has the form of [math]Ae^{-i \omega t}[/math] so when you multiply by the complex conjugate the result is [math]A^2[/math] and it doesn't depend on time

Uhu and how do you explain the electron being in different positions when I measure it 2 times with delay in-between if it doesnt move?

>This is because the wavefunction has the form of Ae^-iωt
It doesn’t. It’s a bound state. The form you gave is for a free state (zero potential). And the wavefunction of that bound state isn’t time-dependent.

You measurement localizes the wavefunction to these two points. It’s not an instantaneous process. You can calculate the rate of decoherence if you want.

Uhu and if I localized in two different positions I have constraines the path of the electron to a line since there is no acceleration right?

There is “acceleration” (useless term in QM) since you interact with the system to measure it.

Aha so now you admit there IS acceleration. Then where is the photon?

Depends on how you measure the system. But at that point, it has nothing to do with the system in question which you had already disturbed.

It follows from your argunebt heisenberg's uncertainty principle has nothing to do with reality and everything to do with measurements

Maybe in your crackpot mind. I don’t see how anything I’ve said relates to the uncertainty principle. Didn’t even mention momentum once.

Electron spins so fast it emits photon in counter phase and both photons cancel each other.

the electron can be in two places at the same time, that's why you can detect it in two different positions without having moved

You said it depends on how I measure, obviously the electron has a momentum I can measure.

This is an important question. Let’s ignore the Bohr orbits, and state the electrons in stationary states have energies defined by the Schrödinger equation, in which, as Schrödinger originally wrote, the total energy is obtained from an entity ψ. What this means is that ψ has the properties of a wave, and hence a wavelength, and from de Broglie, the momentum, and thus the kinetic energy, is defined by that wave length. The electron cannot obey the Schrödinger equation and radiate electromagnetic radiation as required by Maxwell’s equations; the two cannot be completely obeyed at the same time. If you are only interested in an epistemic approach (shut up and calculate) there is no further problem - we know it follows the Schrödinger equation so, er, shut up and calculate.

If you want an ontological answer, that is, a physical reason for why this occurs, you won’t get one that everyone agrees with, and it is not easy to find one that is not even accepted. The one I offer is from my ebook “Guidance Waves”. This is a bit like the pilot wave, except I add the proposition that the physical wave only interacts with the particle (and vice versa) when, following Euler, the complex wave function becomes real, which is at the antinode, and when then action occurs as a discrete unit of h. In the stationary state, the electron only has physical constraints then, and if the antinode does not move, the state cannot change energy. It is whether the antinode accelerates, not the electron. You probably won’t agree with that. Most others do not because it requires the wave to be a physical entity.

Yes. And? That momentum doesn’t change until you measure it. You’re going
>gotcha, if I measure it, it emits light
and I say “so what?” You have already altered the state of the system from just the atom on its own to an external source interacting the atom.

Your entire longpost boils down to “I have never read about semiclassical EM or QED”. Every introductory grad-level QM book goes through it. See Sakurai for example.

normalfags love appealing to authority. I witnessed PhD students fail to answer high school questions at their defenses. Knew a guy who couldn’t name Standard Model coupings at his defense who is now a Princeton postdoc in an experimental group.

Does that mean there's a minimum acceleration?

Electrons don't have a position before being measured so they can't accelerate.
