An on–off ratchet:(a) the particles are located in an energyminima, (b) the potential is turned off so that diffusion can occurfor a short time, and (c) the potential is turned on again. As thepotential is asymmetric, particles have a greater probability of beingtrapped in an adjacent well to the right of the original one thanto the left. (d) Relaxation into the local energy minima leads tothe average position of the particles moving to the right.128

Mentions: In pulsatingratchets, potential-energy minima and maxima are varied in a periodicor stochastic manner with no reference to the position of the particleon the potential-energy surface.128 Thesimplest form is an on–off ratchet where the potential is repeatedlyturned on and off more rapidly than the diffusion of the Brownianparticles over their potential energy surface. This results in thenet directional transport of particles across the surface (Figure 3).
