论文摘要
Majorana绑定状态可以在链的两端的两个稳定性和分离状态的形式中以一维链来实现。在本文中，我们讨论了在系统的一端涂抹电势的情况。在我们的研究中，我们假设位置二次函数的涂抹。我们表明，涂抹的潜力导致额外的间隙状态的出现，并有效地减少了局部间隙（围绕污迹的电位）。主要国家仍保存在系统中，但是它们的定位取决于涂抹。此外，在存在涂抹电势的情况下，不再保留从系统的两侧的主要状态对称定位。
The Majorana bound state can be realized in one dimensional chain, in form of two well localized and separated states at both ends of the chain. In this paper, we discuss the case when the potential is smeared at one end of the system. In our investigation, we assume the smearing in form of a quadratic function of position. We show that the smearing potential lead to the emergence of extra in-gap states, and effectively decrease the local gap (around the smeared potential). The Majorana states are still preserved in the system, however, their localization depend on the smearing. Moreover, the symmetric localization of the Majorana states from both side of the system is no longer preserved in the presence of the smearing potential.
