[Pw_forum] LO-TO splitting in complete phonon dispersion using PWSCF

[Kondaiah Samudrala]

Dear all,

I am looking to know the possibility of asr  rule for non zero q point
(along any other special point from GAMMA direction) ???? Is it
possible???. If no, How can PWscf phonon dispersion plots contains LO-TO
splitting in whole phonon dispersion relation!!!!!

Help me in this doubt... Thanks in advance
