[Pw_forum] phonon wih GGA and LSDA

[Mansoureh Pashangpour]

Dear all
I'm using phonon calculation for a system. I would like to know do
calculated phonon modes change within GGA and LSDA calculation?
and which of them is closer to experimental results?
I would like to know the answer before testing of both calculation.
regards
