aiida-kkr

AiiDA plugin for the Jülich KKR codes plus workflows and utility.

Features

• KKR calculations for bulk and interfaces
• treatment of alloys using VCA or CPA
• self-consistency, DOS and bandstructure calculations
• extraction of magnetic exchange coupling parameters (J_ij, D_ij)
• impurity embedding solving the Dyson equation

Installation

$ pip install aiida-kkr  # install latest version of aiida-kkr (published on pypi.org)
$ reentry scan -r aiida  # update entry points, needed in order to find kkr.* entrypoints in aiida

# setupt aiida if this was not done already:
$ verdi quicksetup  # better to set up a new profile
$ verdi calculation plugins  # should now show kkr.* entrypoints

To install the developer version download the repository and install the downloaded version (see setup.json for a list of optional packages that are installed with the extras given in [])

$ git clone https://github.com/JuDFTteam/aiida-kkr.git
$ pip install -e aiida-kkr[testing,devtools,docs]
$ reentry scan -r aiida

Remarks about dependencies and extras

• The aiida-kkr plugin uses the ase and pymatgen packages for structure conversions.
• For aiida-core>=1.5,<1.6 make sure to use the requirements specified in requirements_aiida-core_1.5.txt (use pip install -r requirements_aiida-core_1.5.txt aiida-kkr for the installation to overwrite the aiida-core dependency).
• Other extras that can be optionally installed with aiida-kkr are
  • pre-commit which installes the pre-commit hooks that allow style (yapf) and static code checking (pylint)
  • testing which installs pytest and all extension used in the tests
  • docs which installs Sphinx to build the documentation
  • devtools which installs tools that might be helpful during development

Usage and Documentation

• see http://aiida-kkr.readthedocs.io for user’s and developer’s guides and API reference
• check out http://judft.de and https://jukkr.fz-juelich.de for information of the KKR codes used by the plugin

Releasing new versions

To create a new release follow these steps:

• finish your development and merge it into the develop branch
• update documentation
• update / fix tests
• bump version numbers (in files aiida_kkr/__init__.py, pyproject.toml, .bumpversion.cfg)
• merge changes from develop back into master and create a tag for the new version number (this triggers publication to pypi)
