Fourier-Legendre expansion of the one-electron density-matrix of ground-state two-electron atoms

Sebastien Ragot, Maria Belen Ruiz

The density-matrix rho(r, r') of a spherically symmetric system can be expanded as a Fourier-Legendre series of Legendre polynomials Pl(cos(theta) = r.r'/rr'). Application is here…

Comments on the momentum density and the spatial form of the density-matrix of the Hooke's atom

Ragot Sebastien

In a recent paper, A. Akbari, N. H. March and A. Rubio [Phys. Rev. A. 76, 032510 (2007)] have investigated the one-electron reduced density-matrix and the momentum density of sever…

Exact Kohn-Sham versus Hartree-Fock in momentum-space: examples of two-fermion systems

Sebastien Ragot

The question of how density functional theory (DFT) compares with Hartree-Fock (HF) for the computation of momentum-space properties is addressed in relation to systems for which (…
