摘要
We investigate the Andreev transports through a double-dot Y-shaped junction with Majorana zero mode. It is observed that the additional direct coupling between the dots plays a nontrivial role in manipulating the Andreev transports. Due to its existence, finite magnetic flux can be introduced through this structure to adjust the local and crossed Andreev reflections in different ways. As a result, changing the interdot coupling is able to enhance the crossed Andreev reflection and weaken the local one at the same time in both the linear and nonlinear transport regions. Such a work can be helpful for controlling the Andreev transport behaviors related to Majorana bound state.
