明确构造了一维Hubbard开链的Lax对。我们的构造为该模型的量子可积性提供了另一种直接的证明。进一步得到了与模型可积性相容的两类边界k矩阵。这似乎有助于在模型的哈密顿函数中产生不同的边界项。
The Lax pair for the one-dimensional (1D) Hubbard open chain is explicitly constructed. Our construction provides an alternative and direct demonstration for the quantum integrability of the model. As a further result, we obtain its two kinds of boundary K-matrices compatible with the integrability of the model. It seems to contribute to the different boundary terms in the Hamiltonian of the model.
