论文摘要
密度功能理论通常是根据构型空间中的密度来制定的。还研究了动量空间密度的功能,并且可以考虑其他密度。我们从第二定量的角度提供了统一的视图,并引入了一个密度功能理论的版本,该理论可以准确地处理所有单粒子的贡献。附录涉及半经典特征值。
Density functional theory is usually formulated in terms of the density in configuration space. Functionals of the momentum-space density have also been studied, and yet other densities could be considered. We offer a unified view from a second-quantized perspective and introduce a version of density functional theory that treats all single-particle contributions to the energy exactly. An appendix deals with semiclassical eigenvalues.
