Abstract
We investigate the Andreev reflection in the heterostructure formed by the indirect coupling between the metallic lead and Majorana zero mode (MZM) via one quantum dot which suffers from the electron-phonon interaction. Our calculation results show that at the zero-temperature limit, the MZM-governed zero-bias conductance value is independent of the electron-phonon interaction. However at finite temperature, the electron-phonon interaction exacerbates the suppression of the magnitude of zero-bias conductance. We believe that the results in this work can help to further differentiate the signature of the MZM in the Andreev reflection process.
