Title: Inequivalent quantizations of the N=3 Calogero model with scale and mirror-S{sub 3} symmetry

Abstract

We study the inequivalent quantizations of the N=3 Calogero model by separation of variables, in which the model decomposes into the angular and the radial parts. Our inequivalent quantizations respect the 'mirror-S{sub 3}' invariance (which realizes the symmetry under the cyclic permutations of the particles) and the scale invariance in the limit of vanishing harmonic potential. We find a two-parameter family of novel quantizations in the angular part and classify the eigenstates in terms of the irreducible representations of the S{sub 3} group. The scale invariance restricts the quantization in the radial part uniquely, except for the eigenstates coupled to the lowest two angular levels for which two types of boundary conditions are allowed independently from all upper levels. It is also found that the eigenvalues corresponding to the singlet representations of the S{sub 3} are universal (parameter-independent) in the family, whereas those corresponding to the doublets of the S{sub 3} are dependent on one of the parameters. These properties are shown to be a consequence of the spectral preserving SU(2) (or its subgroup U(1)) transformations allowed in the family of inequivalent quantizations.
