The eigenfunctions of this operator are the eigenfunctions of the Laplacian which vanish at the scatterer, together with a set of new eigenfunctions (perturbed eigenfunctions). We first show that for a point scatterer on the standard torus all of the perturbed eigenfunctions are uniformly distributed in configuration space. Then we investigate the same problem for a point scatterer on a flat torus with some irrationality conditions, and show uniform distribution in configuration space for almost all of the perturbed eigenfunctions.", "revisions": [ { "version": "v3", "updated": "2012-12-19T15:22:16.000Z" } ], "analyses": { "keywords": [ "point scatterer", "three-dimensional torus", "perturbed eigenfunctions", "configuration space", "three-dimensional flat torus" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013AnHP...14.1801Y" } } }
