How to use Yambo for calculating temperature dependent electronic energy levels in the Heine Allen Cardona approach

  1. I first generate the yambo input file yambo_ph -g n -s p -V qp
  2. Then I set the temperature with the flag BoseTemp. I will name this input file accordingly –>yambo_${T}.in
  3. It is possible to get the HAC energy just for specific bands and k-points by selecting them in
%QPkrange             # [GW] QP generalized Kpoint/Band indices
k1| k1| b1| b2|
k2| k2| b1| b2|

4. Run the previously generated input file,
yambo_ph -F yambo_${T}.in -J ${T}K.
