Abstract :
We study spin-density wave (SDW) in polymers, using screened Coulomb potential to describe full electron interaction in the broad-band systems and developing a spin-dependent correlated-basis-function method to handle the correlation effect. The SDW is shown to be sensitively enhanced with shortening interaction range and suppressed by the correlation effect.
