Brownian rectifiers in the presence of temporally asymmetric unbiased forces.


The efficiency of energy transduction in a temporally asymmetric rocked ratchet is studied. Time asymmetry favors current in one direction and suppresses it in the opposite direction due to which large efficiency approximately 50% is readily obtained. The spatial asymmetry in the potential together with system inhomogeneity may help in further enhancing the… (More)
