Within an one-dimensional tight-binding model, we investigate the inelastic scattering processes of oppositely charged polarons in conjugated polymers under the influence of an external electric field, by using a nonadiabatic evolution method. It is found that the polaron pair does not...

Dynamical formation processes of self-localized excitations induced by charge injection or photoexcitations in a polyacene chain are investigated by a nonadiabatic dynamic method. The polyacene chain is treated as two alternatively coupled polyacetylene chains. The initial lattice configuration...

In this paper, we consider hazard function models with a change-point allowing for random censoring when the base-line hazard function is unknown with some parameters. A non-parametric estimator of the change-point is proposed in the context of counting process. The estimators of change-point...

In a polymer chain, an extra electron or hole distorts the chain to form a charged polaron, which is the charge carrier being responsible for conductivity. When an intermediate-strength electric field is applied, the polaron will be accelerated for a short time and then move at a constant...

Combining the one-dimensional tight-binding Su-Schrieffer-Heeger (SSH) model including interchain interactions and the extended Hubbard model (EHM), we investigate the recombination processes between two triplet excitons in conjugated polymers using a nonadiabatic evolution method. Due to the...
