Coexistence of a Soliton and a Polaron in Trans-Polyacetylene

抄録

In terms of the Takayama-Lin-Liu-Maki continuum model, exact solution is constructed for a polyacetylene chain on which a soliton and a polaron coexist, using the inverse scattering method. It is found that soliton and polaron can freely pass each other without attractive or repulsive interactions, irrespective of their charge and spin. On the basis of the results obtained, elementary processes associated with soliton and polaron in lightly doped trans-polyacetylene are discussed.
