We show that the observed pseudogap in the density of states can be understood as the result of an infrared catastrophe in a noninteracting electron model. This catastrophe stems from the response of an electronic system to the potential produced by the abruptly added charge during a tunneling event. Our formalism can be applied at any filling factor without the use of Chern-Simons or composite fermion theory.", "revisions": [ { "version": "v1", "updated": "2007-02-09T11:27:53.000Z" } ], "analyses": { "keywords": [ "fractional quantum hall system", "infrared catastrophe", "two-dimensional interacting electron gas", "composite fermion theory", "quantizing magnetic field" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
