Densities, density-functionals and electron fluids
Physics Reports, 1982Abstract This review article discusses, from a unified standpoint, three current approaches in applied quantum mechanics that adopt the single-particle density as a basic variable, viz. density-functional theory (DFT), quantum fluid dynamics (QFD) and study of the properties of a system through “local” quantities in three-dimensional (3D) space ...

The Journal of Chemical Physics, 1987
A new method to extract atomic electron momentum density from the corresponding electron density has been proposed. The method is based upon the nonlocal density approximation (NLDA) due to Gunnarsson, Jonson, and Lundqvist; and to Alonso and Girifalco.

Phosphaalkenes with Inverse Electron Density
European Journal of Inorganic Chemistry, 2000This review gives an account of the syntheses, structures, and properties of phosphaalkenes (RP)-P-1=(CRR3)-R-2 with an inverse electron distribution at the P-C double bond (Pdelta-Cdelta+). The chemical reactivity of compounds of this type is novel and quite surprising compared to the chemistry of "classically polarized" phosphaalkenes (Pdelta+Cdelta-)

The Electron Density in Intermediate Scales
Communications in Mathematical Physics, 1997The density of the ground state of large neutral atoms described by Hamiltonians with Coulomb potentials between the electrons and the static nucleus of charge \(Z\) at the origin is investigated.

Theory of electron-electron scattering at low density
Physical Review B, 1993Recent experiments have measured the rate of thermalization due to electron-electron scattering in GaAs at excitation densities below 10 15 cm -3 . Below approximately 5×10 13 cm -3 , the rate of thermalization becomes independent of the carrier density.

Electron Densities and Reduced Density Matrices
1980In the present lectures we are concerned with the use of the bound-state solutions of the time-independent Schrodinger equation $$\text{H}\psi \text{=E}\psi $$ (1) to provide a conceptual and mathematical framework for the analysis and interpretation of the experimentally observed electron densities (charge, spin, and momentum) which are the ...
