Octopus is capable of using different formats for pseudopotentials (seefor more information). We include in the distribution some LDA Troullier-Martins pseudopotentials for some common atoms, but it is likely that you will need other pseudopotentials.
Repositories on the web
These are places on the web that include pseudopotential files in a variety of formats. Note that not all formats are read by Octopus but many are.
- NNIN Virtual Vault for Pseudopotentials Contains an extensive list of pseudo-potential databases and a search engine. It also has links to pseudo-potential related tools.
- ABINIT has a quite complete set of pseudopotentials. At this moment only .fhi files are supported.
- PWSCF's format is also accepted. So you can use the norm-conserving pseudopotentials from their repository. Note that version 2.0 or any later version of the UPF file format are not supported by Octopus currently.
In order to generate your own pseudopotentials, we advise the use of the following programs:
