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…

Strong-coupling superconductivity in layered nickel-based LaOFNiAs
Z. Li, G. F. Chen, J. Dong +8
A series of layered nickel-based LaOFNiAs compounds with x=0 to 0.15 are synthesized by solid state reactions. The pure LaONiAs exhibits bulk superconductivity with Tc…

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…
