In this extension procedure, one requires the Wronskian between any states in the spectrum to approach to the same limit as $x\\to\\pm\\infty$. Then the boundary terms cancel and the Hamiltonian operator can be shown to be hermitian. Discrete bound states with even and odd parities are obtained. Since the Wronskian is not required to vanish asymptotically, the energy eigenstates could be degenerate. Some explicit examples are given and analyzed.", "revisions": [ { "version": "v2", "updated": "2008-06-06T14:35:59.000Z" } ], "analyses": { "keywords": [ "hamiltonian operator", "symmetric potentials", "self-adjoint extensions", "discrete bound states", "boundary terms cancel" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2008, "month": "Jun", "volume": 41, "number": 25, "pages": 255308 }, "note": { "typesetting": "RevTeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008JPhA...41y5308C" } } }
