摘要By starting with the antiferromagnetic chain model, it has been set up that the coupled nonlinear equations describe the interaction between the lattice displacement and the electronic wave function. We obtain an analytic solution of the equation of motion and study the nonlinear dynamics of polyacetylene by considering the Hubbard interaction. The influence of the Hubbard potential upon the parameters of the soliton such as the effective mass and hall-width of the lattice kink has been revaluated. With increasing Hubbard potential, the dimerization and half-width will increase bur the effective mass will decrease.
