I guess I didn't explain my problem very well. In a BE condensate you have indistinguishable bosons with identical wave functions. The problem is now, how can you separate them? The separation is meant to be that the bosons get non identical wave functions. I can't really imagine how to handle...

A question occurred to me concerning the Bose-Einstein condensate: When you have a quantum gas of bosons at a low temperature you obtain a Bose-Einstein condensate where some bosons are in the same state. When you consider the two bosons with the same state, they should behave like one boson...

I was wondering about a question in qm: Who can apply the operator on a wave function to measure an observable? Is it only granted to human beings, which can't apparently not right, because we measure with particular devices or can "everything" measure? If so, wouldn't it implies that there is...
