The $p_{x}+ip_{y}$ Chiral Superconductor wire weakly coupled to two   metallic rings pierced by an external flux
  We consider a p-wave superconductor wire coupled to two metallic rings. confined to a one-dimensional wire. At the two interface between the the wire and the metallic rings the pairing order parameter vanishes, as result two zero modes Majorana fermion appear. The two metallic rings are pierced by external magnetic fluxes. The special features of the Majorana Fermions can be deduced from the correlation between the currents in the two rings.
