Abstract

The dynamical mode-locking phenomena in the overdamped one-dimensional Frenkel-Kontorova model subjected to a parametrized deformable periodic substrate potential and driven by an ac force are examined. When the shape of the substrate potential starts to deviate from the standard one, new subharmonic steps are found to appear in the response function, even in the structures with an integer value of the average interparticle distance, while the critical depinning force can even decrease for some values of the system parameters.
