Resonance and Anti-resonance in transport through quantum dots-Majorana bound states hybrid structure

Abstract

We calculate the linear conductance through a double quantum-dot system with a normal metal lead, which is enclosed in a closed shape where quantum dot-1 is connected to Majorana bound states (MBSs). The Quantum dots configuration from parallel to series allows for a transition in the shape of resonant to non-resonant in the spectrum. This is caused by quantum interference between the energy levels. This process results in the formation of bonding and antibonding states that are involved in electron transport. An asymmetric quantum dots configuration can produce a Fano resonance, and its position can be adjusted by altering the energy levels.
