摘要: Nonlinear dynamics of the sliding process a chain driven with constant velocity at one end in periodic substrate potential is investigated. The exhibits distinctly different dynamical characteristics velocities. In low region, moves stick–slip manner. When driving increased, behaviour replaced by complicated and regular oscillatory motions. dependence on coupling strength studied step-like found, where steps correspond to phases.
