Exact Solutions of a One-dimensional Quantum Spin Chain with SO(5)-Symmetry
Yuzhu Jiang, Junpeng Cao, Yupeng Wang
A new exactly solvable one-dimensional spin-3/2 Heisenberg model with SO(5)-invariance is proposed. The eigenvalues and Bethe ansatz equations of the model are obtained by using th…

Conservation laws of the Haldane-Shastry type spin chains
Junpeng Cao, Peng He, Yuzhu Jiang +1
A systematic method to construct the complete set of conserved quantities of the Haldane-Shastry type spin chains is proposed. The hidden relationship between the Yang-Baxter relat…
