Estimating the Accuracy of the Variational Energy: The Hydrogen Atom in a Magnetic Field as an Illustration
J. C. del Valle
For a hydrogen atom subject to a constant magnetic field, we report a numerical realization of the two-dimensional Non-Linearization Procedure (NLP) to estimate the accuracy of the…

High-Order Harmonic Generation in Helium: A Comparison Study
A. T. Bondy, S. Saha, J. C. del Valle +4
We report a detailed study of high-order harmonic generation (HHG) in helium. When comparing predictions from a single-active-electron model with those from all-electron simulation…
