ARPES spectra from electron-phonon calculation
Posted: Sun Jan 06, 2019 4:05 am
Dear all,
I am relatively new to ABINIT and I am currently struggling with what should be a post-processing step to an electron phonon calculation:
I want to calculate the electron spectral function usually denoted as A(k,w) (w being omega, the energy), that is the property probed by angle-resolved photoemission spectroscopy (ARPES). For each k-point (k) and Kohn-Sham energy (e_KS) I need the frequency-dependent electron-phonon self-energy. If I am not mistaken I have the ingredients after an electron phonon run but I am wondering if there is a way to collect this in a plot-able format using anaddb (or another tool I might not be aware of)?
Thanks for your help and sorry for this basic question!
Best,
Chris
