Abstract: Directed transport of an active polymer chain with chirality is investigated in a transversal asymmetric channel. The polymer chain is composed of a chiral active particle and several passive particles. Due to the interplay of the chirality of the chain and the transversal asymmetry, the polymer chain can be rectified. The direction of the transport is determined by the competition of the chirality of the chain and the properties of the channel. Remarkably, we can observe current reversals by varying the system parameters such as self-propelled speed, the chirality, the length of the chain, and the channel parameters. Our finds are relevant to the experimental pursuit of the controlling of the active polymer in periodic channel.
