摘要
Correlation effects in the excited state of conjugated polymers are investigated. In the presence of an additional electron or hole, the correlation induces a polarization cloud around the additional particle, which forms a polaron. For the excitation energy of a polaron, there is a competition between a loss of the correlation energy and a gain of the polarization energy. The calculation on correlation effects of the band gap has been done for both the Hubbard model and long-range interactions.
