Interaction effects on a Majorana zero mode leaking into a quantum dot
Interaction effects on a Majorana zero mode leaking into a quantum dot
We have recently shown [Phys. Rev. B {\bf 89}, 165314 (2014)] that a non--interacting quantum dot coupled to a one--dimensional topological superconductor and to normal leads can sustain a Majorana mode even when the dot is expected to be empty, \emph{i.e.}, when the dot energy level is far above the …
