Full Counting Statistics of Chiral Majorana Fermions — Alexander Schuray, •Luzie Weithofer, and Patrik Recher — TU Braunschweig, Institute for Mathematical Physics, Braunschweig

In recent years many detection schemes for chiral Majorana fermions interferometers [1] in which the current or noise is used to identify the Majorana character of the propagating edge states have been proposed. Here, we derive a general formalism to find the general transport properties for chiral Majorana fermions coupled to normal leads. For this we employ Full Counting Statistics [2-3], a Keldysh-technique based method, to find the so-called cumulant generating function (CGF), an expression that gives an insight into the elementary transport processes and from which the full statistics of the current can be obtained by differentiation. Our method reproduces the known results of different interferometers, like Fabry Perot [4] or Hanbury Brown-Twiss [5] in a concise way. Finally, we apply it to a three-terminal setup and discuss its transport properties.
