Electron Phonon Coupling example

Post by ypan » Thu Sep 09, 2021 12:34 pm

Dear All,

In the example of Electron Phonon Coupling (http://www.yambo-code.org/wiki/index.ph ... n_Coupling), it said that "Notice that the last column in the quasi-particle file "o.QP" contains the quasi-particle width, that is related to their life-time" below the figure of "Si gap at various T". However, how to obtain the o.QP file? It seems that this example loses some important infortmation about this point.

Thanks.

Best,

Dear Yipeng,
the o.qp file is generated by running yambo_ph with the input file generated by:
yambo_ph -g n -p fan -c ep -V gen

as indicated in the tutorial.

Best,
