We propose to study noise correlations in a Hanbury Brown-Twiss type interferometer and find three signatures of the Majorana nature of the channels. First, the average charge current in the outgoing leads vanishes. Furthermore, we predict an anomalously large shot noise in the output ports for a vanishing average current signal. Adding a quantum point contact to the setup, we find a surprising absence of partition noise which can be traced back to the Majorana nature of the carriers.", "revisions": [ { "version": "v1", "updated": "2011-09-02T09:39:23.000Z" } ], "analyses": { "subjects": [ "71.10.Pm", "73.23.-b", "74.45.+c" ], "keywords": [ "majorana fermion edge states", "transport experiments", "noise signatures", "interferometric", "topological insulator support transport channels" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "doi": "10.1103/PhysRevLett.107.136403", "year": 2011, "month": "Sep", "volume": 107, "number": 13, "pages": 136403 }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011PhRvL.107m6403S" } } }
