Wave Function Identity: A New Symmetry for 2-electron Systems in an Electromagnetic Field
Marlina Slamet, Viraht Sahni
Stationary-state Schr{ö}dinger-Pauli theory is a description of electrons with a spin moment in an external electromagnetic field. For 2-electron systems as described by the Schr{ö…
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…
Criticality of Electron-Nucleus Cusp Condition to Local Effective Potential Energy Theories
Xiao-Yin Pan, Viraht Sahni
Local(multiplicative) effective potential energy theories of electronic structure comprise the transformation of the Schr{ö}dinger equation for interacting fermi systems to model n…
