AbstractThe problem of propagation for quasiparticles on a dimerized chain which is modeled by alternating site energies and intersite interactions is investigated. Exact solutions for the propagators, the mean polarization and mean-square displacement are obtained, from which the role of the site-energy mismatch and hopping disturbance on the behavior of the moving particle can be clearly seen. It is demonstrated that the increase of the site-energy mismatch and the hopping disturbance will lead to the enhancement of the localization.
