{"abstract":[{"lang":"eng","text":"We present conductance-matrix measurements in long, three-terminal hybrid superconductor-semiconductor nanowires, and compare with theoretical predictions of a magnetic-field-driven, topological quantum phase transition. By examining the nonlocal conductance, we identify the closure of the excitation gap in the bulk of the semiconductor before the emergence of zero-bias peaks, ruling out spurious gap-closure signatures from localized states. We observe that after the gap closes, nonlocal signals and zero-bias peaks fluctuate strongly at both ends, inconsistent with a simple picture of clean topological superconductivity."}],"isi":1,"publisher":"American Physical Society","type":"journal_article","related_material":{"record":[{"relation":"research_data","id":"13080","status":"public"}]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","day":"15","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2006.01275"}],"oa":1,"title":"Closing of the induced gap in a hybrid superconductor-semiconductor nanowire","intvolume":"       103","external_id":{"isi":["000661512500002"],"arxiv":["2006.01275"]},"date_published":"2021-06-15T00:00:00Z","citation":{"apa":"Puglia, D., Martinez, E.
