Fundamental characteristic property of particles which together with orbital angular momentum acts as the generator of rotations and which doesn't have a classical equivalent but is sometimes compared to and contrasted with classical intrinsic angular momentum.

Total spin in a multiparticle system
I know that if I have a single fermion then the expectation value of the spin along the $\hat{n}$ direction can be computed by $\sigma \cdot \hat{n}$, where $\sigma_i$ are the pauli matrices.
Now if …

How does the Pauli exclusion work on fermions but not on bosons?
The relation between spin and the exclusion principle is called the spin statistics theorem, but I don't think there is an elementary explanation for it (other than doing the math).
Plancks constant …

Are there two different spinors for the same spin state?
Yes they are, and not only those two but there are infinitely many vectors representing the same physical state. Don't forget that physical states in QM are represented by rays in Hilbert space. So in …
