What is Multiple Current Reversals and Negative Differential Mobility Induced by a Periodic Kick Force about?
Anomalous transports of a particle in the action of periodic kick force are investigated. By means of numerical simulations, it is found that average velocity (or current) of the particle can be controlled completely by magnitude, period and action time of the kick force. As the kick force is deterministic, direction of the current changes several times with the action time of the kick force if the other parameters remain unchanged, i.e., a multiple current reversals phenomenon. For some optimal action time, there exists a multiple negative differential mobility (NDM) phenomenon, what's more, the NDM segments are much more than those in the case of constant bias force. If the action time of the periodic kick force is stochastic, the multiple NDM phenomenon also appears in the curve of the current versus the kick force. And segment number of the NDM increases with the additive frequency of the gating potential and the frequency of the kick force. It is worth noting that whether the kick force is deterministic or stochastic, the multiple NDMs can take place in the region of greater kick forces compared with the case of constant bias force. The results will possess a crucial significa
