The initial state corresponds to a discrete eigenvalue which dives into the continuous spectrum and re-emerges from it as the dot energy is varied in time and finally returns to its initial value. Our main result is that for a large class of couplings, the survival probability of this bound state vanishes in the adiabatic limit.", "revisions": [ { "version": "v1", "updated": "2016-12-07T18:13:33.000Z" } ], "analyses": { "keywords": [ "adiabatic theorem", "eigenvalues dive", "survival probability", "bound state vanishes", "dot energy varies" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
