  title = {Screening models and simplified GW approaches - Si and GAN as test cases},
  abstract = {We compare models of diagonal and off-diagonal screening with LDA-RPA full calculations in Si and cubic GaN. Simplified GW calculations relying on these models are also compared with full GW calculations for the same materials. A recipe for simplified GW calculations is obtained which works well for small, moderate and wide gap semiconductors.},
