Recombination Dynamics

The intrachain recombination dynamics between oppositely charged polarons is theoretically investigated through the use of a version of the Su–Schrieffer–Heeger (SSH) model modified to include an external electric field, an extended Hubbard model, Coulomb interactions, and temperature effects in the framework of a nonadiabatic evolution method.
