Signatures of an expected topological phase transition accompanying the onset of these modes nevertheless remain elusive. We investigate a fundamental question concerning this issue: Do well-formed Majorana modes necessarily entail a sharp phase transition in these setups? Assuming reasonable parameters, we argue that finite-size effects can dramatically smooth this putative transition into a crossover, even in systems large enough to support well-localized Majorana modes. We propose overcoming such finite-size effects by examining the behavior of low-lying excited states through tunneling spectroscopy. In particular, the excited-state energies exhibit characteristic field and density dependence, and scaling with system size, that expose an approaching topological phase transition. We suggest several experiments for extracting the predicted behavior. As a useful byproduct, the protocols also allow one to measure the wire's spin-orbit coupling directly in its superconducting environment."}],"article_number":"245404","quality_controlled":"1","oa":1,"year":"2016","publication_status":"published","day":"08","main_file_link":[{"url":"https://arxiv.org/abs/1601.07908","open_access":"1"}],"date_published":"2016-06-08T00:00:00Z","citation":{"apa":"Mishmash, R., Aasen, D., Higginbotham, A.
