Long-distance coherence of Majorana wiresExport this event to calendar

Webex Seminar - Zheng Shi, Free University of Berlin

A one-dimensional topological superconductor hosts a pair of Majorana bound states at its ends, forming a fermionic level which stores the fermion parity information nonlocally. Consequently, in the Coulomb blockade regime, Majorana-assisted single-electron tunneling can remain coherent well beyond the coherence length of the superconductor. In this talk, we show that the finite propagation velocity of charge degrees of freedom places a limit on the long-distance coherence; in particular, charge dynamics may strongly suppress coherent single-electron transport in a semiconductor wire proximitized by superconducting islands
