| 中文摘要 | An exactly solvable one-dimensional ferrimagnetic quantum spin chain model with alternating 1/2-spins and 1-spins is proposed and solved via algebraic Bethe ansatz. It is found that the ground state of this model is a ferrimagnetic state with a residual magnetization. It is proven that the low-lying elementary excitations of the system are the varieties of gapless spinons rather than spin waves. |
