# Phonix: Database for Anharmonic Phonon Interactions

## About

Phonix is a first-principles database of anharmonic phonon interactions.

Phonix v2026.03.28 targets approximately 20,000 inorganic, non-metallic, and 
non-magnetic compounds drawn from the Materials Project (v2022.10.28) and Phonondb (v2018-04-07), 
including thermal conductivity data for over 6,800 materials.

The database was generated using the automated workflow software
[auto-kappa](https://masato1122.github.io/auto-kappa "auto-kappa") 
([GitHub](https://github.com/masato1122/auto-kappa "github")),
which integrates VASP and ALAMODE for first-principles
anharmonic phonon calculations.
