Abstract:

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 2e2 / 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.

Key words: Majorana fermions, gauge invariance, quantized conductance
