How to remove small negative frequencies near Gamma

WebThe phonon calculations using a finite differences approach are carried out by setting IBRION=5 or 6 in the INCAR file. When these flags are set the second-order force … WebPhonopy sorts the frequencies by magnitude, so we can just skip the first three and four for the initial and transition states, respectively. We take them at q=0. Mantina et al. (PRL … highest gni asean
