Phonopy phonon band
WebPlot phonon band structure and fix the ordering problem in Phonopy WebDec 2, 2024 · 1 Answer. There are two major techniques used to model phonon interactions - The frozen phonon method and density functional perturbation theory (DFPT). Phonopy is used to carry out calculations in the frozen phonon scheme. ProfM does a fantastic job delineating the differences between the two methods here.

First we need to prepare some input files for phonopy. … WebJan 1, 2024 · The PhononUnfolding program reads parameters max_qx, max_qy and max_qz, and gets the plane wave basis. The basis functions are used to get the projection operator . From which, we finally obtain the phonon unfolding weight. The calculation results are stored in file unfold.dat, which can be plotted by using Origin or Gnuplot.
