| 中文摘要: |
| 把用 Pauli算符表示的哈密顿量转化成用Hubbard 算符表示.利用Hubbard 算符的归一性和正交性给出了Hubbard 算符 和Pauli算符之间转化的运算公式,从而实现了哈密顿量表示方式的转化,得到了用Hubbard 算符表示的自旋梯模型的哈密顿量.利用自旋梯模型的哈密顿量做为例子,完成了用 Pauli算符表示的哈密顿量转化成用Hubbard 算符表示. |
| 英文摘要: |
| Aiming at the transformation of Hamiltonian from Pauli matrices to Hubbard operators, the authors use the unity and orthogonal of Hubbard operators to give the transforming formula of Pauli matrices and Hubbard operators, by which, they realize the change from Pauli matrices to Hubbard operators.The result has been obtained that the Hamiltonian expressed by Hubbard operators of the spin-ladder model. |
