Waiting time distributions in quantum spin Hall based heterostructures

We study the scattering processes and associated waiting time distributions (WTDs) in heterostructures based on one-dimensional helical edge states of a two-dimensional topological insulator. In combination with proximitized $s$-wave superconductor an applied magnetic field transition occurs. Along this WTD reveals specific features related to presence Andreev bound at finite energy or Majorana zero under ideal conditions. The effects several imperfections such as disorder temperature are discussed.
