| contents | We show that nonzero drag current in a double quantum-dot system, consisting of a biased drive dot and an unbiased passive dot coupled capacitively, can be generated by a Majorana bound state located at one of the leads connected to the passive dot. Importantly, the drag current induced by Majorana bound states, either an isolated Majorana bound state or two weakly coupled but spatially separated Majorana modes, shows qualitative differences from that induced by a near-zero-energy Andereev bound state. Thus, other than the tunneling spectroscopy, the proposed setup can serve as a complementary tool to detect Majorana fermions in proximitized Rashba nanowires. |
