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...

What is the wave the answer to? Does it represent an individual physical system or an ensemble or something only mathematically or...

On one hand, a minimal view of quantum mechanics is to see the Schrödinger equation and wavefunction as part of a description for a...
