Modern norm-conserving pseudopotentials are constructed such that the scattering properties of the all-electron atom are reproduced around the reference energy configuration up to first order in energy, following pseudopotentiale procedure described in [Hamann][Hamann]and [Troullier].

Abinit employs iterative eigenvalue solvers to solve the KS equations. See Version Compatibility below if you get an "End of File" error with abinit.

The total nonlocal part of the Hamiltonian is obtained by summing the different atom-centered contributions. Old legacy pseudopotential tables can be find here.

Users should test them adequately before using them in their applications. Documents and tools outdated.

For simplicity, the discussion is limited to pseudopotentials with a single projector per angular channel. Current version of the library: For the generalization of norm conservation to multiple projectors Optimized norm-conserving Vanderbilt pseudopotentials we refer the reader to [Hamann]. Clicking on a green cell in the periodic table will bring you into a directory corresponding to the selected chemical element.

In modern ab initio codes, the fully separable Pseusopotentials form, proposed by Kleynman and Bylander, is usually employed as it drastically reduces the number of operations required for the application of the nonlocal part of the Hamiltonian as well as the memory required to store the operator [Kleinman].

The generalization to multi-projector pseudopotentials requires introducing an additional n index in the KB energies i.

For question and remarks please contact Michiel van Setten or Matteo Giantomassi. This page reports the basic definitions and equations needed to evaluate the nonlocal part of the Hamiltonian. The tar file contains a script to do this for all pseudo potential files. Tables for LDA and pseudopotentizls relativistic calculations are currently being prepared.

The results of these test for the standard set are summarized in the following table. Note For simplicity, the discussion is limited to psfudopotentials with a single projector per angular channel. The final expression in real space reads:.

Pseudopotentials

Table of contents Pseudopotentials in the Aabinit Bylander form. The 'low' hint would be a good point to start your convergence study, the 'normal' hint can be used as a relatively safe value for a quick single calculation, the 'high' hint can be used for ultimate convergence testing.

We mainly pseudolotentials on norm-conserving pseudopotentials. The size of a dataset file psp8 may vary between 50 kB and kB. Note Abinit employs iterative eigenvalue solvers to solve the KS equations.

For our purpose, we can summarize by saying that a pseudopotential is constructed in order to replace the atomic all-electron potential such that core states are eliminated and valence electrons are described by pseudo wavefunctions whose representation in the Fourier space decays rapidly.

Providing a consistent introduction to the theory of pseudopotentials is beyond the pseudopotetnials of this section, a more complete discussion of the topic can be found in specialized articles available in the literature [Hamann][Bachelet][Kleinman][Hamann][Troullier] [Gonze][Fuchs]. These sets are available as lists of pseudos one per abinut in the main folder.
