Determination of Wave Function Functionals: The Constrained-Search--Variational Method
Xiao-Yin Pan, Viraht Sahni, Lou Massa
In a recent paper [Phys. Rev. Lett. \textbf{93}, 130401 (2004)], we proposed the idea of expanding the space of variations in variational calculations of the energy by considering…
Bijectivity of the Normalization and Fermi-Coulomb Hole Sum Rules for Approximate Wave Functions
Xiao-Yin Pan, Viraht Sahni, Lou Massa
We prove the bijectivity of the constraints of normalization and of the Fermi-Coulomb hole charge sum rule at each electron position for approximate wave functions. This bijectivit…
The constrained-search--variational method: application to the ground state of Helium atom
Xiao-Yin Pan, Viraht Sahni, Lou Massa
n a recent paper we proposed the expansion of the space of variations in energy calculations by considering the approximate wave function to be a functional of functions $χ: ψ=…
Determination of a Wave Function Functional
Xiao-Yin Pan, Viraht Sahni, Lou Massa
In this paper we propose the idea of expanding the space of variations in standard variational calculations for the energy by considering the wave function to be a functional o…
On the Hylleraas Coordinates
Xiao-Yin Pan, Viraht Sahni, Lou Massa
The Hylleraas coordinates , , are the natural coordinates for the determination of properties of the Helium atom, the po…
