Description
Phonopy is an open source package of phonon calculations based on the supercell approach.
- Phonon dispersion relation (band structure)
- Phonon DOS and partial-DOS
- Phonon thermal properties, free energy, heat capacity, and entropy
- Phonon group velocity
- Thermal expansion and heat capacity at constant pressure within quasi-harmonic approximation (phonopy-qha)
- Mode Grüneisen parameters (gruneisen)
- Non-analytical-term correction, LO-TO splitting (Born effective charges and dielectric constant are required.)
- Animation of normal modes for crystal viewers
- Characters of irreducible representations of normal modes
- Crystal symmetry tools
- Python module (Phonopy can be used in python script.)
- Graphical plots
