# The cuboctahedric Higgs oscillator from the rational Calogero model

@article{Hakobyan2008TheCH, title={The cuboctahedric Higgs oscillator from the rational Calogero model}, author={Tigran Hakobyan and Armen Nersessian and Vahagn Yeghikyan}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2008}, volume={42}, pages={205206} }

We exclude the center of mass of the N-particle rational Calogero model and consider the angular part of the resulting Hamiltonian. We show that it describes the motion of the particle on an (N − 2)-dimensional sphere interacting with N(N − 1)/2 force centers with Higgs oscillator potential. In the case of a four-particle system, these force centers define the vertexes of an Archimedean solid called a cuboctahedron.
