    Have Majorana zero modes been observed in superconductor-semiconductor devices?, G. Katsaros (seminar talk),
    20.10.2023, Atominstitut, TU Wien, Vienna
    Hybrid semiconductor–superconductor devices hold great promise for realizing Majorana zero modes [1-3]. However, multiple claims of Majorana detection, based on either tunnelling or Coulomb blockade (CB) spectroscopy, remain disputed. In this talk I will introduce an experimental protocol that allows to perform both types of measurement on the same hybrid island by adjusting its charging energy via tunable junctions to the normal leads [4,5]. This method reduces ambiguities of Majorana detections by checking the consistency between CB spectroscopy and zero-bias peaks in non-blockaded transport. I will discuss the theoretical interpretation of the experimental observations in terms of low-energy, longitudinally confined island states rather than overlapping Majorana modes. The results highlight the importance of combined measurements on the same device for the identification of topological Majorana zero modes.
