Like.
Interestingly, in the non-relativistic limit of QFT, they still remain operators. It is possible to formally recover the states of... -
LarryS reacted to Matterwave's post in the thread Undergrad Particles' Intrinsic Properties in QFT with Like.
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...

LarryS reacted to anuttarasammyak's post in the thread Undergrad Why is a Gaussian function used to represent a wave packet? with Like.
A Gaussian wave packet has the property that its width increases with time while its overall shape is preserved. This behavior is...
