Dear Quantum Espresso users, I'm still trying to figure out how to run gw calculations. In particular, I need help to understand better how to create a pw4gww input. 1) Do you always suggest to use optimal polarizability basis? 2) numw_prod is a keyword working only in case of pmat_type=5 (as suggested from the gwl manual) or is it a keyword that works always (as I understand reading the gwl tutorial)? 3) If i want to perform gw calculation developing polarizability operators on a basis set with 3 Ry for the energy cutoff and selecting 1000 most important basis vectors, which are the keyword I have to set up? 4) Are there more tutorials available about gw calculation with more explanations about the outputs?
Thank you really much for your help. Valentina Cantatore PostDoc Researcher@Università del Piemonte Orientale
