Shot noise in a Majorana fermion chain

Understand

We calculate the shot noise power in a junction of a network of Majorana bound states (MBS) with a normal metal.

• These Majorana bound states are on the border of alternative ferromagnetic and superconducting regions at the quantum spin Hall insulator edge.
• We analyze different realization of MBS networks including a few isolated ones or in a chain allowing for the limit of weak and strong tunneling.
• The conductance, as well as the shot noise are considerably stronger than those of a weakly coupled normal-superconduting junction, being a hallmark of the MBS.
