Calogero模型的立方八面体Higgs振子

Cuboctahedric Higgs oscillator from the Calogero model

T. Hakobyan, A. Nersessian, V. Yeghikyan

摘要:

我们排除了N粒子有理Calogero模型的质心,并考虑由此产生的哈密顿量的角度部分。我们证明了它描述了粒子在(N-2)维球上与N(N-1)/2个力心相互作用的运动。在四质点系统中,这些力心定义了一个称为立方八面体的阿基米德固体的顶点。

英文摘要:

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 (N-2)-dimensional sphere interacting with N(N-1)/2 force centers with Higgs oscillator potential. In the case of four-particle system these force centers define the vertexes of an Archimedean solid called cuboctahedron.
