Re: Electron-phonon intro: plots of el-ph matrix elements on k-BZ and q-BZ

Dear Fulvio,
Many thanks for your reply and clearing many of our doubts. At this point, we can generate exciton-phonon matrix elements over the BZ similar to Fig. 3(lower panel) in the paper: https://journals.aps.org/prl/abstract/1 ... 125.107401
However, in the code excphondb.py, (after some more lines from our side) we can plot only average G_nm(Q,q). We can print all the G_nm(Q,q) and average G_nm(Q,q). We would also like to find out the exciton-phonon scattering rate (upper panel of Fig. 3). Can you let us know how we can proceed for reading the energies and matrix elements from the file?
Regards,
Sitangshu
