Yambo Post Processing (ypp)

YPP is a post-processing tool included in the Yambo distribution.
In this tutorial we present a non-exhaustive list of the things that can be calculated with this tool.

• Brillouin Zone:
  
  • -k p → write the k-point list in different format
  • -k q → write the q-point list in different format
  • -k s → generate shifted k-points grid
  • -k h → write the highest symmetry points in the BZ
  • -k r → generate random k-points in the BZ
  • -k e → generate regular k-points grids

 -map             (-m)            :Fine to coarse grid Map

• Convertions:

-fixsym          (-y)            :Remove symmetries not consistent with an external perturbation
-qpdb                 <string>   :Quasiparticle Databases (more with -h qpdb)

• Plots:

-BSiq            (-b) <int>      :Excitonic State Momentum
-electron        (-s) <string>   :Electronic properties (more with -h electron)
-exciton         (-e) <string>   :Excitonic properties (more with -h exciton)
-dipoles              <string>   :Dipole properties (more with -h dipoles)
-freehole                        :Free hole position in the excitonic plot
-avehole                         :Average hole/electron wavefunction

• SOC:

-soc             (-w)            :Perturbative SOC mapping
