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.

量子点-马约拉纳束缚态混合结构输运中的共振与反共振

我们通过带有普通金属引线的双量子点系统计算线性电导,该系统封闭在封闭形状中,其中量子点-1 连接到马约拉纳束缚态 (MBS)。量子点配置从并联到串联允许光谱中谐振形状到非谐振形状的转变。这是由能级之间的量子干涉引起的。该过程导致电子传输中涉及的键合和反键合态的形成。不对称的量子点配置可以产生法诺共振,并且可以通过改变能级来调整其位置。
