PH-NODE is a Python 3 based code designed for finding topological phonon nodes (branch-degenerate points) in a material using first-principle approach. It is a density-functional perturbation theory and finite displacement supercell based software package for efficiently computing phonon nodes present in real material. The present version of the code is interfaced with the WIEN2k, Elk, and ABINIT packages.
Please cite the paper mentioned below while using the PH-NODE code for your research.
