Help and feedback
Create an issue on the GitHub site or contact the developers of the potential you are interested in.
Thanks for contributing! Please create a pull request on the GitHub site from a forked and branched copy of the repo. Please include details of the published papers or preprints where the potentials will be fully described. Create an issue for help with this or to discuss a contribution.
- Now that H-Kr are complete, additional elements will be added based on requests. Create an issue if you need an element.
- As implementations of spin-orbit are made in many-body codes such as QMCPACK, appropriate formats will be determined and new potentials incorporating spin-orbit will be added.
