We find a lack of the full equilibration across the edge even in the flat-band situation, where no potential barrier survives at the sample edge. We interpret this result as the manifestation of complicated edge excitation structure at high fractional filling factors 4/3, 5/3. Also, a mobility gap in the $\\nu_c=1$ incompressible strip is determined in normal and tilted magnetic fields.", "revisions": [ { "version": "v1", "updated": "2007-11-08T11:41:21.000Z" } ], "analyses": { "keywords": [ "fractional quantum hall regime", "complex edge excitation structure", "high filling factors", "high fractional filling factors", "manifestation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0711.1251D" } } }
