Majorana零偏压量子化电导的规范不变性

The gauge invariance of Majorana zero-bias quantized conductance

从规范不变性出发,利用电子与空穴散射对称性,推导出Majorana零偏压量子化电导平台的值为2 e 2/h,得到的结果与现有理论相同,表明出现Majorana零偏压量子化电导平台的本质原因是规范不变性.

Based on the gauge invariance and the symmetry of electron and hole scattering,the value of Majorana zero-bias quantized conductivity platform is deduced to be 2 e 2/h.The result is the same as the existing theory.It is shown that the essential reason for the appearance of Majorana zero-bias quantized conductivity platform is based on the gauge invariance.
