WebJul 11, 2024 · Dear hiPhive developer, I am a new user of hiPhive and would like to apply the rotational sum rule on the 2nd order force constant of two-dimensional material. After getting the force_constants.hdf5 file by phonopy I used the following script to generate a further corrected force file. from ase.io import read from hiphive import ClusterSpace, … Webafter running the phonopy there will be a kappa-mXXXX.hdf5 and using that you can simply calculate and plot phonon life time with: phono3py-kaccum --qe --pa="F" -c Si.in kappa-mXXXX.hdf5
WebDec 26, 2024 · I am using the hiphive tool to obtain “fc2.hdf5” from FORCE_CONSTANTS.
