通过明确构造具有相同单矩阵本征值谱但不同双矩阵的反例,我们表明,仅仅基于单矩阵本征值的电子能密度矩阵泛函是不可能的(句子似乎不完整)
By explicit construction of counterexamples having the same eigenvalue spectrum of one-matrix, but different two-matrix, we show that density-matrix functionals for the electronic energy that are based solely on the eigenvalues of the one-matrix cannot be unique in functional representation of the two-matrix. The one-to-many mapping may be understood either through the number of independent parameters or the contraction relation.
