Class of exactly solvable SO(n) symmetric spin chains with matrix product ground states
Hong-Hao Tu, Guang-Ming Zhang, Tao Xiang
We introduce a class of exactly solvable SO(n) symmetric Hamiltonians with matrix product ground states. For an odd case, the ground state is a translational invariant Ha…

String order and hidden topological symmetry in the SO(2n+1) symmetric matrix product states
Hong-Hao Tu, Guang-Ming Zhang, Tao Xiang
We have introduced a class of exactly soluble Hamiltonian with either SO(2n+1) or SU(2) symmetry, whose ground states are the SO(2n+1) symmetric matrix product states. The hidden t…
