aiida-vibroscopy

AiiDA plugin that uses finite displacements and fields to compute phonon properties, dielectric, Born effective charges, Raman, non-linear optical susceptibility, and Pockels tensors, coming with lots of post-processing tools to compute infrared (absorption and reflectivity) and Raman spectra in different settings.

Installation

To install from PyPI, simply execute:

pip install aiida-vibroscopy

or when installing from source:

git clone https://github.com/bastonero/aiida-vibrosopy
pip install .

Command line interface tool

The plugin comes with a builtin CLI tool: aiida-vibroscopy. For example, the following command should print:

> aiida-vibroscopy launch --help
Usage: aiida-vibroscopy launch [OPTIONS] COMMAND [ARGS]...

  Launch workflows.

Options:
  -v, --verbosity [notset|debug|info|report|warning|error|critical]
                                  Set the verbosity of the output.
  -h, --help                      Show this message and exit.

Commands:
  dielectric      Run an `DielectricWorkChain`.
  harmonic        Run a `HarmonicWorkChain`.
  iraman-spectra  Run an `IRamanSpectraWorkChain`.
  phonon          Run an `PhononWorkChain`.
