I am very disappointed by my experiment on this site. Four days ago, I posted this question: Numerical simulation of the double-slit experiment including watching the electrons . After less that 24 hours, it was put [on hold] by 5 persons as being unclear. So I edited my question a first time in the hope the [on hold] would be removed so that people can answer it, unfortunately it remained in the [on hold] state. I read from the rules that "Questions that are not reopened within five days will change from [on hold] to [closed]", so I went deeper in reading the rules from page https://physics.stackexchange.com/help/reopen-questions where it is suggested to re-edit the question and "Flag the question for moderator attention. Again, explain why it should be reopened. There is more than one moderator, and moderators do reconsider their decisions". So I followed these steps, re-edited the question a second time and flagged the question, explaining the moderator why in my opinion the question should be reopened. I was then surprised to get the following answer from a moderator: "declined - flags should only be used to make moderators aware of content that requires their intervention". Hence either he or me does not comply to the stackexchange policy... being novice here I guess that it is my fault, but could someone explain me what I did wrong?
All in all, I am very disappointed: I have now spent many hours having to justify myself for asking a question which, unless I am completely stupid, has clearly some interest, and lost hope of getting an answer. I write it here again for information:
The double-slit "thought experiment" described by Feynman in Lectures on Physics Volume 3 section I-6 Watching the electrons consists in firing electrons through a double-slit to observe the interference of electron waves, and watching them after passing the slits with a light source placed behind the double-slit, at equal distance of each slit. As electric charges scatter light, one can "detect" which slit the electron went through if the photon wavelength is small enough.
Question: has this "thought experiment" been simulated by solving numerically the underlying Schrödinger equation? I am aware about numerical experiments of the double-slit, but did not find any including the interaction between the electrons and the photons just after the double-slit.
The numerical simulation can address other types of particles, the crucial point being the simulation of the observation (here the photons being scattered by the electrons) and its effect on the wavefunction. Its interest could be in particular to better understand in which precise way the observation progressively becomes inoperative when the photon wavelength increases.
