| 英文摘要 | The quantum coherent motion of excitons (electrons) in a dimerized chain with one impurity is studied analytically. The exact solutions for the amplitude propagators are obtained explicitly, from which the effects of the impurity and the electron-phonon interaction (which models the dimerized chain) are manifested. The evolution of excitons is found to be more and more localized with the increase of the impurity energy or the enhancement of the electron-phonon interaction. The symmetry property for the amplitude propagators in the real space is also given. |
