Static screening

Static screening matrix

Create the input file:

$ yambo -F 02_Ws.in -b -k hartree     (for a 3D material)

or

$ yambo -F 02_Ws_2D.in -b -k hartree -r  (for a 2D)

Open the input file Change the size in G-space and the bands of the polarization function as:

% BndsRnXs
  1 |  40 |                 # [Xs] Polarization function bands
%
 NGsBlkXs= 2 Ry  # [Xs] Response block size

Close the input and run the code

$ yambo -F 02_Ws.in  -J 3D

or

$ yambo -F 02_Ws_2D.in -J 2D
