Polarizability matrix for exciton-phonon coupling and luminescence

Post by hmzhang9 » Wed Dec 04, 2024 7:24 am

Dear all,

I am trying to get polarizability matrix for exciton-phonon coupling and luminescence. May I ask how can I set in my input file?

Thanks,
Hang-Ming

Dear Prof. Claudio,

Thank you very much for your prompt and insightful response. Following your detailed tutorials, I have successfully reproduced the luminescence spectra of h-BN via QE + yambo-excph.

However, I am currently facing a challenge in extracting the directional matrix output for the luminescence data, which is divided into components such as xx, yy, xy, etc. I hope this clarifies my question.

Thank you once again for your kind support.

Best regards,
Hang-Ming
