# Holstein-Primakoff realizations on coadjoint orbits

@article{Oh1997HolsteinPrimakoffRO, title={Holstein-Primakoff realizations on coadjoint orbits}, author={Phillial Oh and Chaiho Rim}, journal={Modern Physics Letters A}, year={1997}, volume={12}, pages={163-172} }

We derive the Holstein–Primakoff oscillator realization on the coadjoint orbits of the SU(N+1) and SU(1,N) group by treating the coadjoint orbits as a constrained system and performing the symplectic reduction. By using the action-angle variables transformations, we transform the original variables into Darboux variables. The Holstein–Primakoff expressions emerge after quantization in a canonical manner with a suitable normal ordering. The corresponding Dyson realizations are also obtained and… Expand
