comment Can spin-1/2 emerge as a property of quasiparticles if original description of the system was without spin?
Consider meta-atoms of metamaterials with magnetic interaction. The plasmonic excitations of the metal may be assumed to be bosonic, but the excitations of each meta-atom may be described, on the single-photon-level, as a quasiparticle with spin. I think there are related examples condensed matter physics.

comment Dipole Moment of Collection of Harmonic Oscillators
Are the oscillators coupled? If not, what can you do? Look up "rotating wave approximation". Good luck.
