Competition between polaron and bipolaron in conjugated polymers with nondegenerate ground state is systematically studied in the extended Hubbard-Peierls model with the symmetry-breaking Brazovskii-Kirova term, using the density matrix renormaliz...

We calculate rates of excitation-energy transfer (EET) from B800 to B850 within the light-harvesting antenna complex LH2 of photosynthetic purple bacteria. The calculation is based on anew formula which incorporates EET interactions between transi...

Interchain hopping of solitons and polarons in polyacetylene is studied by numerical simulation of their motion under an electric field. Use is made of the Su-Schrieffer-Heeger model supplemented with intrachain electron-electron interactions and ...

Third-order nonlinear optical spectra chi((3)) Of conjugated polymers are theoretically studied within the treatment of double-excitation configuration interaction for the Pariser-Parr-Pople model. We consider a realistic situation of dephasing ra...
