  • We present a study of the transmission of electrons through a semiconductor quantum wire with strong spin-orbit coupling in proximity to an $s$-wave superconductor, which is Coulomb blockaded. Such a system supports Majorana zero modes in the presence of an external magnetic field. Without superconductivity, phase lapses are expected to occur in the transmission phase, and we find that they disappear when a topological superconducting phase is stabilized. We express tunneling through the… CONTINUE READING
