| 英文摘要 | The quantum coherent motion of excitons (quasiparticles) in a chain with alternating site energies (model A) or intersite interactions (model B) is studied analytically. Exact solutions for the mean polarizations and the mean-square displacements for both systems are obtained explicitly, from which an inherent symmetry between the two models is revealed. It is found that the effects of the site-energy mismatch and the hopping disturbance to the diffusing behavior of the moving quasiparticles are almost identical. Similarities and differences for the two models are manifested in these analyses. |
