| 中文摘要 | The high-spin ultracold atomic models with a special form of contact interactions, i.e. the scattering lengths in the total spin-2, 4, ... channels are equal, but may be different from that in the spin-0 channel, are studied. Those models have either U(1) circle times Sp(2s + 1)-symmetry for the fermions or U(1) circle times SO(2s + 1)-symmetry for the bosons, and the generators are found to be magnetic multipole operators. Based on the symmetry analysis, a class of exactly solvable models is proposed and solved via the Bethe ansatz. The ground states and excitations for repulsive fermions are also discussed. |
