We investigate elastic scattering processes of a negative polaron and a negative(or positive) bipolaron,and calculate the charge carrier mobility in a conjugated polymer chain in the presence of an external electric field.The dynamical simulations are performed based on the Su-Schrieffer-Heeger(SSH) model modified to include electron-electron interactions and a Brazovskii-Kirova symmetry-breaking term.
