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.","lang":"eng"}],"date_updated":"2021-01-12T06:47:42Z","publist_id":"7952","status":"public","external_id":{"arxiv":["1601.07908"]},"date_created":"2018-12-11T11:44:38Z","author":[{"last_name":"Mishmash","first_name":"Ryan","full_name":"Mishmash, Ryan"},{"full_name":"Aasen, David","last_name":"Aasen","first_name":"David"},{"first_name":"Andrew P","orcid":"0000-0003-2607-2363","last_name":"Higginbotham","full_name":"Higginbotham, Andrew P","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Alicea, Jason","first_name":"Jason","last_name":"Alicea"}]}
