We investigate the localization of spinwaves by coupling to a scalar disorder potential via their topological density. A low energy description of the system in terms of a non-linear sigma model of unitary supermatrices is derived. All states of this model are localized in two dimensions. A possible experimental signature of these effects in photo-luminescence is suggested.", "revisions": [ { "version": "v1", "updated": "1998-09-30T10:23:56.000Z" } ], "analyses": { "keywords": [ "quantum hall ferromagnet", "localization", "non-linear sigma model", "low energy description", "scalar disorder potential" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
