We investigate the different regimes that emerge when a periodic driving force, the rocking force, acts on a collective feedback flashing ratchet. The interplay of the rocking and the feedback control gives a rich dynamics with different regimes presenting several unexpected features. In particular, we show that for both the one-particle ratchet and the collective version of the ratchet an appropriate rocking increases the flux. This mechanism gives the maximum flux that has been achieved in a ratchet device without an a priori bias.
我们研究了周期性驱动力（即摇摆力）作用于集体反馈闪烁棘轮时出现的不同状态。摇摆力与反馈控制的相互作用产生了丰富的动力学，不同状态呈现出几个意想不到的特征。特别是，我们表明，对于单粒子棘轮和棘轮的集体版本，适当的摇摆都会增加通量。这种机制给出了在没有先验偏差的棘轮装置中所能达到的最大通量。
