Probing Majorana fermions in one-dimensional topological superconductors using non-equilibrium transport: an open-quantum-system study

We study one-dimensional topological superconductors using an open-quantum-system approach based on Langevin equations. We go beyond a low-energy effective model of Majorana fermions, to derive different non-equilibrium transport properties exactly in these systems. The role of the coupling between the superconducting wire and metallic leads in physical experiments to detect Majorana bound states is also examined.
