This is not a duplicate. I am not asking about quantum leaps or quantum jumps or whether the transition is instantaneous (yes I asked that question before here Do electrons really perform instantaneous quantum leaps?).
I have read this question:
Where cmaster says:
When an electron falls from one shell to a lower one, it's wave function transitions smoothly from one eigenvector to another, creating a superposition of the two eigenvectors with changing amplitudes. This superposition wave function has the property of oscillating precisely with the frequency of the emitted photon. It's the expected location of the electron that oscillates. So, electron relaxation actually falls within the accelerated charge case.
where Kyle Oman says:
So what does the electron do between observations? I don't think anyone can answer that question. All we can say is that at one time the electron was observed at point A, and at a later time it was observed at point B. It got from A to B... somehow. This leads to a different way of thinking about where an electron (or other particle) is.
where annav says:
As far as the mathematics goes there is only the probability and no continuity between two space points so that a classical velocity could be defined.
So basically one says that electron relaxation is an accelerating charge.
The other ones say, that the electron's position is not even classically defined during the transition, it is in a superposition and not even velocity could be calculated, thus I believe we cannot talk about the acceleration of the electron during relaxation.
This is a contradiction, because as per QM, the wavefunction transition goes smoothly, creating a superposition. Now I believe it does not make sense to talk about classical speed or acceleration in this superposition of states.
- Is the relaxing electron really accelerating or not?
