eigenstate

1.Each eigenstate of an observable corresponds to an eigenvector of the operator, and the associated eigenvalue corresponds to the value of the observable in that eigenstate.

每个可见特符合操作者一特，而相关特符合特可见。

2.The Bethe ansatz equations are obtained from the periodic boundary conditions.The results show that this system is also completely integrable.

【摘要】： 正 The exact eigenstates of the Hamiltonian of the mixed-valence lattice model are constructed by using the Bethe ansatz.
