Create the input
yambo -F 03_bse_Ws_wcut.in -b -r -o b -k sex -V QP 03_bse_Ws_wcut.in
Open it and change some of the input variables
BSENGexx= 30 Ry # [BSK] Exchange components BSENGBlk= 2 Ry # [BSK] Screened interaction block size
In the excitonic hamiltonian the GW energies are required. If you have already generated a ndb.QP database you can read it
KfnQPdb= " E < ./SAVE/ndb.QP " # [EXTQP BSK BSS] Database
or you can give the numerical value of the GW scissor and conduction and valence streaching.
For this material appropriate velues are:
% KfnQP_E 1.00000 | 1.000000 | 1.000000 | # [EXTQP BSK BSS] E parameters (c/v) eV|adim|adim %
