The issue has become more clearer now and I think these posts misses the point. It is not about individual elementary particles at all...

I can agree with that. p.s. Post 8 was not really relevant at all, but lets leave that

It's trivial in QFT. Ordinary QM is only an approximation to the relativistic limit of QFT. There are no antiparticles in ordinary...

It is not just a choice. By describing it as an individual physical system, it is being overlooked that every such physical system is...

Because elementary particles are identical. The indistinguishability is a consequence of that. A photon may have a different energy...

It is not about describing a single elementary particle, but about an individual physical system. Let me guess, you never had a real...

No, there is no such requirement indeed. Thus you are trying to describe with a wave function a system and interpretate it as an...

Indistinguishable particles in two different states, here and there for example, are still indistinguishable.

You have corrected me and rightfully so for not taking sufficient time for it. It is very difficult to express these things. Elementary...

OK, during the weekend I had some time to think it over. The electrons cannot be labeled if they each have a probability for presence...

A more direct answer is to realise that ordinary non-relativistic QM (QM) is incorrect - our best current theory is Quantum Field Theory...

Usually it's taken to refer to the viewpoint that you can do QM without having to adopt any interpretation: you just do the math and...

Yes, I understand that. You cannot label them if the different electrons have a probability to be in the same position in such a quantum...

Indeed wave function, just being sloppy. From the reference given earlier (Ballentine): (II) Interpretations which assert that a pure...

I agree that QFT should bring better answers. The implications on what you might still be able to tell on macroscopic level could be...
