Abstract
In this work we show that optimal ratchet currents of two interacting particles are obtained when stable periodic motion is present. By increasing the coupling strength between identical ratchet maps, it is possible to find, for some parametric combinations, current reversals, hyperchaos, multistability, and duplication of the periodic motion in the parameter space. Besides that, setting a fixed value for the current of one ratchet it is possible to induce a positive/negative/null current for the whole system in certain domains of the parameter space.
