- 論文の詳細を見る
Linear modes around a soliton and a polaron are calculated after static self-consis-tent solutions for a soliton and a polaron are numerically determined in Su-SchriefferHeeger's (SSH) model of Zran,s'-polyacetylene [7-(CH).1 with finite size. The linearchain is assumed to satisfy the periodic boundary condition. In the case of a soliton,four localized modes are found, three of which correspond to the localized opticalmodes obtained in the continuum version of the SSH model and the fourth appearsbecause of the discreteness. In the case of a polaron, the number of the localizedmodes is seven; five have been already obtained in the con1.inuum model and the re-maining two are generated due to the discreteness.
