AE and PS radial wavefunctions $\phi(r)$

fig = plotter.plot_radial_wfs(show=False)

Arctan of the logarithmic derivatives

From oncvpsp documentation: The plots show $\phi(E) = \arctan(R * d \psi(r)/dr |_R)$ for some $R$ greater than the core radius, where $\psi$ is the solution of the non-local radial equation regular at the origin (i.e., the outward-integrated solution). For a well-designed pseudopotential, $\phi(E)$ will closely track that of the all-electron potential over a wide range of energies from well-below to well-above the valence semi-core states of interest. The steps of $\pi$ indicate localized pseudo wave functions. Spurious steps of $\pi$ indicate "ghost" states, which are localized states than on investigation turn out to have more nodes than appropriate for their energies.

For $GW$ pseudos, no significant deviation should be present up to 8 Hartree.

fig = plotter.plot_atan_logders(show=False)

Convergence in $G$-space estimated by ONCVPSP

These results are obtained in the atomic configuration and should give a reasonable estimate of the convergence behaviour wrt to ecut in crystalline systems.

fig = plotter.plot_ene_vs_ecut(show=False)

Projectors

In general the second projector in any channel should have one node more that the first one. Pushing the energy of the second projector too high may cause an additional node. This will most likely introduce ghosts.

fig = plotter.plot_projectors(show=False)

Core-Valence-Model charge densities

Much better convergence properties can been achieved with icmod 3. In this case, fcfact mainly determines the height of the model core charge while rcfact mainly determines the width of the model core charge.

fig = plotter.plot_densities(show=False)

Local potential and $l$-dependent potentials

fig = plotter.plot_potentials(show=False)

Ghosts Test

Self-consistent band structure calculation performed on a regular mesh. The algorithm to detect ghosts is just an indication usually on the side of false positives. Zoom in on the band plot to see if an actual ghost is there.

Convergence of the Delta-Gauge results

The Delta-gauge compares the Equation Of State (EOS) of the elemental solid of the element calculated using the pseudo potential to reference curves calculated using an all electron method. The Delta-gauge was introduced by K. Lejaeghere, V. Van Speybroeck, G. Van Oost, and&S. Cottenier in Critical Reviews in Solid State and Materials Sciences 39, 1

A comparison using the Delta-gauge between many codes and many pseudo tables can be found at the center for molecular modeling and in Science 351, 1394-1395

Convergence of the GBRV lattice parameters

The GBRV tests compare the lattice parameter of a FCC and BCC lattice of the element to all electron reference data. The test was introduced by Kevin F. Garrity, Joseph W. Bennett, Karin M. Rabe, and David Vanderbilt in developing th GBRV pseudo potential table. More information can be found in Computational Materials Science 81, 446-452.
