Dear all, I am very much interested in knowing LA-TA modes and grunessian parameter calculations using pwscf.
Is it possible to get non zero acoustic modes at Gamma point. Because, If I am applying asr rule at gamma point, the acoustic modes are zero in my case. How can we define LA-TA modes ??? Is degenerative modes (Out of First three modes) are transverse modes??? How to do grunessinn parameter calculations for entire phonon spectrum in PWscf??? Hope positive reply..Thanks in advance with regards S. Appalakondaiah PhD student University of Hyderabad -------------- next part -------------- An HTML attachment was scrubbed...
