Title: Projected Augmented Wave (PAW) Method with multiple pseudo statesmapped onto the same all electron wavefunction

Authors: Garry Goldstein

Comments: Comments welcome

Subjects: Other Condensed Matter (cond-mat.other); Materials Science (cond-mat.mtrl-sci); Chemical Physics (physics.chem-ph)

The Projected Augmented Wave (PAW) Method is based on generating a transform between the pseudo wavefunction and all electron wavefunction. For the accuracy of the method it is important that the local part of the transform (in each atomic sphere $\mathbf{R}$) be over a complete basis set (with deviations from completeness leading to corrections to the total energy not computed within current implementations of PAW). Here we show how to make this basis much closer to complete without significant additional computational work by allowing for multiple smooth pseudo wavefunction states to be mapped onto the same all electron wavefunction.
