Adiabatic rocking ratchets: Optimum-performance regimes.
We analyze work and efficiency for an adiabatic rocking ratchet working under three operating regimes: maximum efficiency, maximum work, and a third one which represents a compromise between them. For all of these regimes the application of very concrete loads and external amplitudes is found necessary in order to obtain the maximum possible values of both efficiency and work. The reported results could be valuable to design efficient Brownian motors and compare their operation under different working regimes.
