In a perpendicular magnetic field, electrons form bound states around the antidot. Aharonov-Bohm resonances through such bound states have been experimentally studied, showing interesting phenomena such as Coulomb charging, h/2e oscillations, spectator modes, signatures of electron interactions in the line shape, Kondo effect, etc. None of them can be explained by a simple noninteracting electron approach. Theoretical models for the above observations have been developed recently, such as a capacitive-interaction model for explaining the h/2e oscillations and the Kondo effect, numerical prediction of a hole maximum-density-droplet antidot ground state, and spin density-functional theory for investigating the compressibility of antidot edges. In this review, we summarize such experimental and theoretical works on electron interactions in antidots.", "revisions": [ { "version": "v2", "updated": "2007-12-03T15:43:01.000Z" } ], "analyses": { "keywords": [ "integer quantum hall regime", "electron interactions", "hole maximum-density-droplet antidot ground state", "bound states", "kondo effect" ], "tags": [ "journal article", "review article" ], "publication": { "publisher": "Elsevier", "journal": "Physics Reports", "year": 2008, "month": "Feb", "volume": 456, "number": 4, "pages": 127 }, "note": { "typesetting": "TeX", "pages": 73, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008PhR...456..127S" } } }
