Abstract: Standard density functional approximations greatly over-estimate the staticpolarizability of longchain polymers, but Hartree-Fock or exact exchangecalculations do not. Simple self-interaction corrected SIC approximations canbe even better than exact exchange, while their computational cost can scaleonly linearly with the number of occupied orbitals.
