A giant topological magnetoelectric effect is proposed which is characterized by two resonant peaks with half-unit transmissions and rich polarization behaviors in the photonic band gap. We also predict a giant optical Hall effect in our system, in which the transverse shift of the transmitted light could be thousand times larger than the wavelength. These effects are purely from the $\\Theta$-domain walls at the topological insulator interfaces and could be observed easily. These effects can also be used as the sensitive detection of basic physical constants.", "revisions": [ { "version": "v1", "updated": "2011-01-25T07:21:00.000Z" } ], "analyses": { "keywords": [ "topological insulator", "thousand times larger", "rich polarization behaviors", "one-dimensional photonic crystals", "photonic band gap" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1101.4735W" } } }
