首次导出并分析了自然自旋轨道的有效非局域势的显式形式。结果表明,在简并单电子约化密度矩阵的情况下,势不是唯一的。有效势的知识使人们可以建立自然自旋轨道的单电子方程,这对于有效的密度矩阵泛函理论计算可能有很大的价值。
For the first time the explicit form of the effective nonlocal potential for the natural spin orbitals is derived and analyzed. It is shown that in the case of the degenerate one-electron reduced density matrix the potential is not unique. The knowledge of the effective potential allows one to establish one-electron equations for the natural spin orbitals that may be of great value for efficient density matrix functional theory calculations.
