Using Keldysh path-integral approach, we study current fluctuations (shot noise) within the low-energy effective theory. We argue that the combination of the tunneling conductance and the shot noise through a quantum dot allows one to distinguish between the topological (Majorana) and non-topological (e.g., Kondo) origin of the zero-bias conduction peak. Specifically, we show that, while the tunneling conductance might exhibit zero-bias anomaly due to Majorana or Kondo physics, the shot noise is qualitatively different in the presence of Majorana zero modes.", "revisions": [ { "version": "v1", "updated": "2014-09-12T20:24:21.000Z" } ], "analyses": { "subjects": [ "73.21.Hb", "71.10.Pm", "72.70.+m", "74.78.Fk" ], "keywords": [ "quantum dot shot noise experiments", "probing majorana physics", "majorana zero modes", "study transport properties", "zero-bias conduction peak" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.91.081405", "journal": "Physical Review B", "year": 2015, "month": "Feb", "volume": 91, "number": 8, "pages": "081405" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1316570, "adsabs": "2015PhRvB..91h1405L" } } }
