If the orbital angular momentum of an electron in an atomic orbital is associated with (generated by) an asymmetry in the orbital wave function, is it also the case that the intrinsic spin of a free electron (as one specific example) in QFT is associated with an asymmetry in the coherent excitation pattern of the electron matter field/EM field constituting the electron? Or, is intrinsic spin more fundamental, perhaps relating to the fact that the underlying matter field is a spinor field.
