| 英文摘要 | We introduce a class of exactly solvable SO(n) symmetric Hamiltonians with matrix product ground states. For an odd n >= 3 case, the ground state is a translational invariant Haldane gap spin liquid state; while for an even n >= 4 case, the ground state is a spontaneously dimerized state with twofold degeneracy. In the matrix product ground states for both cases, we identify a hidden antiferromagnetic order, which is characterized by nonlocal string order parameters. The ground-state phase diagram of a generalized SO(n) symmetric bilinear-biquadratic model is discussed. |
