AB  - Electron-phonon (e-ph) renormalization effects in a model cuprate system CaCuO2 
      are studied by employing density functional theory based methods. Whereas 
      calculations based on the local spin-density approximation (LSDA) predicts 
      negligible e-ph coupling effects of the half-breathing Cu-O bond stretching mode, 
      the inclusion of a screened on-site Coulomb interaction (U) in the LSDA+U 
      calculations greatly enhances the e-ph coupling strength of this mode. The 
      full-breathing mode, on the other hand, shows a much weaker e-ph renormalization 
      effect.
