On the Applicability of the Frenkel-Kontorova Model to Describing the Dynamics of Vacancies in a Polymeric Crystal Chain
Journal of Experimental and Theoretical Physics vol.93, No.4, pp.895-902 (2001)
Аннотация
The necessary conditions of the applicability of the Frenkel-Kontorova one-dimensional model [the approximation of immobile neighboring chains plus sine-Gordon (continual) equation for nonlinear
dynamics of the chain under consideration] to describing the dynamics of vacancies in a polymeric crystal chain are determined. It is shown that these conditions are satisfied for polyethylene crystals. The physical mechanism of model applicability limitations is established.
