Abstract

We consider the effects of Coulomb interactions on the transport properties of a one-dimensional topological superconductor nanowire hosting Majorana bound states at its ends. The analytic results are derived for the temperature-dependent differential conductance of a grounded nanowire as a function of the Ohmic circuit impedance. For a gate-controlled nanowire, analytic expressions are derived for the rates of single-electron tunneling, local and nonlocal Andreev reflections, and elastic cotunneling. These rates are used in numerical calculations of current-voltage characteristics and differential conductance. The obtained results will be helpful in experimental searches of Majorana signatures in one-dimensional topological superconductors.
