The euphonic-intensity-map
program can be used to plot a 2D intensity
map either along a specific trajectory from precalculated phonon frequencies
and eigenvectors, or along a recommended reciprocal space path from force
constants.
For example, to plot a coherent neutron-weighted intensity map from CASTEP force constants along a recommended q-point path, one could run:
euphonic-intensity-map --weighting coherent --energy-broadening 1.5 quartz.castep_bin
Or, to plot a DOS-weighted intensity from Phonopy phonon frequencies:
euphonic-intensity-map --weighting dos --energy-unit THz --energy-broadening 0.15 band.yaml
To see all the command line options, run:
euphonic-intensity-map -h
