This tutorial works only with Yambo version > 6.x
The exciton-phonon part of Yambo does not support symmetries yet!!!
This an advanced tutorial, in order to calculate exciton-phonon coupling and phonon-assisted absorption/emission you need a deep knowledge of the theory and of the Yambo code. In this tutorial we will calculate phonon-assisted absorption and luminescence including the scattering between exciton and phonon.[1][2][3]
