@article{Oh2019CanonicalQO, title={Canonical Quantization of Noncompact Spin System}, author={Phillial Oh}, journal={Journal of the Korean Physical Society}, year={2019}, volume={74}, pages={1093-1100} }

We consider spin system defined on the coadjoint orbit with noncompact symmetry and investigate the quantization. Classical spin with noncompact SU(N, 1) symmetry is first formulated as a dynamical system and the constraint analysis is performed to reduce the system from the group space to the coadjoint orbit which is a symplectic manifold with Kähler structure. We achieve this by solving the constraint directly. It is shown that the dynamical variables describing the noncompact spins can be…
