Owing to the nonlocal character of the Majorana state, the corresponding excitations are of great interest. It is demonstrated that the direct consequence of such nonlocality is the collapse of the Fano resonance manifesting itself in the conductance of an asymmetric interference device, the arms of which are connected by a one-dimensional topological superconductor. In the framework of the spinless model, it is shown that the predicted effect is associated with an increase in the multiplicity of the degeneracy of the zero-energy state of the structure arising at the critical point of the Kitaev model. Such an increase leads to the formation of a bound state in the continuum.

马约拉那州的非本地性导致的法诺共振崩溃

由于马约拉那州的非本地性，因此引起了人们极大的兴趣。证明了这种非局域性的直接后果是在一个不对称干涉装置的电导中表现出的Fano共振的崩溃，该干涉装置的臂通过一维拓扑超导体连接。在无旋转模型的框架中，表明了预测的效果与在Kitaev模型的临界点出现的结构零能量状态简并性的增加相关。这种增加导致在连续体中形成结合态。
