ypp_ph Phonon-assisted density of states

Post by mrefiore » Thu Sep 16, 2021 9:38 am

Dear YAMBO developers and users,

I'm currently running the latest GPL version available and trying to obtain the phonon-assisted density of states by running

Code: Select all

ypp_ph -e p
However, the produced input file looks "wrong":

Code: Select all

ElecTemp= 0.000000         eV    # Electronic Temperature
BoseTemp=-1.000000         eV    # Bosonic Temperature
StdoHash=  40                    # [IO] Live-timing Hashes
excitons                         # [R] Excitonic properties
infver                           # [R] Input file variables verbosity
States= "0 - 0"                  # Index of the BS state(s)
En_treshold= 0.000000      eV    # Select states below this energy treshold
Res_treshold= 0.000000           # Select states above this optical strength treshold (max normalized to 1.)
BSQindex= 1                      # Q-Index of the BS state(s)
From the tutorial webpage, I get that the line

Code: Select all

ph_ass_dos                       # [R] Phonon-assisted DOS
should be present, and it's not. Indeed, the calculation doesn't work.
What am I missing?
Thank you very much for your help!
Best,


Michele
