Outline of Final Research Achievements

Novel directed motion and transport of nanomachines on a solid surface are studied by numerical simulations and theoretical analyses based on a model at nanoscale. The directed motion is induced by introducing the spatiotemporal modulation into nanomachines. It is found that the dynamical states where the directed motion occurs are classified into two characteristic regimes, i.e., locking regime and unlocking one. The adiabaticity of motion of the nanomachine against the spatiotemporal modulation is essentially important to understand the dynamical behaviors of the present system. For the directed motion under adiabatic conditions, the time-averaged velocity of the nanomachine is locked to a fundamental value. The velocity locking occurs when the amplitude of the spatiotemporal modulation is larger than a certain threshold value. Using a scaling analysis of the threshold of modulation amplitude, we reveal the universal nature of the directed motion.
