[Pw_forum] Phonon dispersion curve

[Masoud Rahbar]

Dear QE users
I am learning how to plot phonon dispersion curves. in phonon examples
there is an example (link below) which calculates the phonon dispersion for
Aluminum the result is shown in the figure below:
but according to the literature, it should have been something like this:

the k path is the same. Could someone help me why there is a difference?
