Not really. Pauli first formulated the exclusion principle in 1925, but then it was just an ad hoc assumption. Proving it required the... -
LarryS replied to the thread Undergrad Particles' Intrinsic Properties in QFT.Maybe this should be a new thread, but how does all of the above tie in with the concept of Identical Particles? The Identical...

Interestingly, in the non-relativistic limit of QFT, they still remain operators. It is possible to formally recover the states of...

Expanding a little. States in QFT live in a Hilbert space. The irreducible subspaces of that Hilbert space has certain symmetries...

I don't think that intrinsic and extrinsic are the right words for what you are trying to say. Perhaps better words are invariant and...

LarryS replied to the thread Undergrad Particles' Intrinsic Properties in QFT.Are the invariant properties part of the unexcited (vacuum state) state of the field?

In single-particle nonrelativistic QM, a particle, say an electron, has intrinsic properties like rest mass, charge and spin magnitude...
