A Novel Formulation of a Local-Scaling Density Functional Theory

抄録

A local-scaling density functional theory (LS-DFT) [J. Phys. Soc. Jpn. 72 (2003) 1926] is reformulated excluding an artificial expression. In the formulation, two kinds of local-scaling transformations are proposed. The basic equation of the LS-DFT is derived. It is shown that the equation is equivalent to the differential virial theorem proposed by Holas and March [Phys. Rev. A 51 (1995) 2040].
