Abstract
We investigate the Aharonov-Bohm (AB) effect in the parallel double-quantum-dot structure, by introducing an additional s-wave superconductor to couple to the quantum dots. It is found that the AB oscillation of the electron tunneling is different from the superconductor-absent result. Meawhile, the local and crossed Andreev reflections exhibit their special oscillation behaviors, with the change of the local magnetic flux. This means that the AB effect plays an important role in manipulating the complicated quantum transport through this system. We believe that this work can be helpful for understanding the AB oscillation in the presence of Andreev reflection processes.
