Current Cross-Correlation in a T-Shaped Quantum-Dot Junction with Majorana Bound States
We investigate the electronic transport characteristics caused by the Majorana bound state,in the T-shaped structure with one topological superconducting nanowire embedded between two quantum dots.By considering both symmetric and asymmetric bias modes,it is found that the superconducting pairing term between the quantum dots has a significant impact on the non-locality of the Majorana bound state.The main manifestation is that,compared to the slight change in conductance,the strength of current cross-correlation is significantly dependent on the bias application manner and the superconducting pairing term between the quantum dots.This indicates that current cross-correlation is an effective way to describe the properties of Majorana bound states.This work contributes to a deeper understanding of the physical properties of Majorana bound states.
