Coulomb blockade of Majorana fermion induced transport
arXiv:1108.4308 · doi:10.1103/PhysRevB.84.165440
Abstract
We study Coulomb charging effects for transport through a topologically nontrivial superconducting wire, where Majorana bound states are present at the interface to normal-conducting leads. We construct the general Keldysh functional integral representation, and provide detailed results for the nonlinear current-voltage relation under weak Coulomb blockade conditions.
