[Phonopy-users] Question about 3-phonon scattering

[Rijan K. <rij...@gm...>]

Hi Phonopy users,

I have a question regarding 3 phonon scattering calculations in phono3py.
I have never calculated it before and would like to know if these
calculations address my question beforehand.

Suppose I want to know how an optical phonon (for example Raman active
phonon) scatters into two different phonons. Do you know if this
calculation will get me this information?
If the answer is yes, once phono3py_disp.yaml, FORCES_FC3 and BORN are
computed, how do I calculate how phonon mode (x cm-1) scatters into
other two phonons? Is there any related tutorial on this?

Thank you.

Rijan
