GBRV Library Garrity-Bennett-Rabe-Vanderbilt library is a library of ultrasoft pseudopotentials for most of the periodic table, with the exception of f-block elements. Go to the Notes section below to learn more about the subfolders in each category. Only energy differences are physically relevant. Smaller is the delta the closer are the results to the all electron calculations. A small restrictions exists in cp. Same for nonlocal e.

Equilibrium volume and bulk modulus comparison for elemental solids between pseudopotential and all electron codes. These pseudopotentials are pre-distributed with JDFTx, and you can access the latest version for any element using the wildcard syntax: In case you inquire for a pseudopotential on the mailing list, please specify which kind of pseudopotential you need norm-conserving, ultrasoft, PAW, full- or scalar-relativistic, for which XC pseueopotential, and, for many elements, with how many electrons in valence.
Schlipf-Gygi library is a library of norm-conserving pseudopotentials for most of the periodic table, with the exception of f-block elements. Here are some results from this work:. There you can find several tables, pointers to other tables, indications on what to do if you do not find the pseudopotential s you need.
JDFTx: Pseudopotentials
If you have no clue: Here are some pseudopotential libraries and generators that work with JDFTx: What I cannot computeI do not understand adapted from Richard P. You can select older versions by explicitly selecting version numbers eg. See the pseudopotential page on this web site. This new set of pseudopotentials are generated and distributed by Prof.
You can pseudopotentiial to use specific versions by explicitly specifying version numbers, eg. Like most other plane-wave codes, JDFTx deals only with the valence electrons. Jon Doe Generation date: Kinetic energy difference between all-electron and pseudo component of each augmentation channel.
How do they perform? We suggest a uniform and symmetric comparison factor, Delta1', extending the works of K.
More about pseudopotentials
The recommanded structure is the following: All-electron wavefunctions used for the generation of quantu dataset; there is one wavefunction for each beta projector. Please have a look at the various links and resources of the pseudopotential page.
As an example, here we demonstrate the performance of some of the transition metals we have tested in the new set: Please consider first if DFT is suitable for your system!
Smaller is the delta the closer are the results to the all electron calculations.
There are nbeta terms, each one containing potential V 1: GGA and the like. Beware, these are huge files. Potentials are multiplied by e so they have the units of energy.
The recommanded structure is the following:. The following files hold the pseudopotentials in UPF format for over 60 elements in the periodic table, that are generated and generously shared by Prof.
2 Pseudopotentials - QUANTUMESPRESSO
Fields that are not defined are ignored. Yes, you can when possible, of course: Currently, three formats of pseudopotentials are supported by JDFTx: Go to the Notes section below to learn more about the subfolders in each category. Same for nonlocal e. The effect of core electrons are handled through the use of pseudopotentials. Note that it is the hardest atom that determines the cutoff.
