Valence bond solid states with symplectic symmetry

We introduce a one-dimensional valence bond solid (VBS) state with symplectic symmetry $\text{SP}(n)$ and construct the corresponding parent Hamiltonian. We argue that there is a gap in the spectrum. We calculate exactly the static correlation functions, which fall off exponentially. Hence the model introduced here shares all properties of the Haldane scenario for integer-spin quantum antiferromagnets. We further show that the VBS state possesses string order and discuss its generalization to… Expand
