Phonopy

Description

Phonopy is an open source phonon analyzer. In principle any code that can calculate forces on atoms can be used together. Features include:

  • Phonon dispersion relation (band structure)
  • Phonon DOS and partial-DOS
  • Phonon thermal properties, free energy, heat capacity, and entropy
  • Thermal expansion and heat capacity at constant pressure within quasi-harmonic approximation

There are built-in interfaces for the VASP and Wien2k as well as a python module for using phonopy in your own programs.

User instructions

Phonopy is available via the modules system. To add it to your environment run:

$ module load phonopy/1.11.12.92

This adds the main phonopy program (called ‘phonopy’) to your environment, along with some more specialised programs. Extensive documentation, examples and tutorials can be found on the phonopy website.
