What we have is the concept of quantum spin being the movement of energy in the field itself NOT the classical particle mass rotating energy. That classical particle rotation can exist in some situations in addition to the quantum spin.
Are we talking about a particle having classical spin and quantum spin? Would both impart angular momentum to the particle?
The key point is that the field can only move at the speed of light that is what sets the velocity for class 0 waves. The fact we can measure the energy in the field as classical angular momentum tells us the energy is behaving like a classical field.
I’m never quite clear about field movement. Should it be seen as the field moving, or something (energy/information/ripples?) moving in the field. If a field already fills space, in what sense does it move?
If a particle can be considered as a particle or a wave, and the particle has angular momentum, can the angular momentum be measures when the observation “shows” a wave? If not, what happens to the angular momentum?
In some sense there is no more important detail in physics because here we have this quantum world suddenly exhibiting a very classical behaviour in that once you start energy in the field rotating it exhibits classical momentum. There are very few Quantum and Classical physics connections and yet here we have one.
Is there a form of rotation that could be considered a quantum momentum, as distinct from classical momentum?
A spin 1 particle has relative field motions at right angles to the direction of motion and will not be able to move at the speed of light with the above restriction, same problem as a tornado moving at its spin speed.
This is spin 1, rather than class 1 particles?
There is actually a much more profound effect that will be obvious as a spin 1 moves faster given that restriction.
Clues?
