This technique can generate the spectrum associated with an arbitrary potential $V(r)$ starting from the analytically known spectrum of a particular potential $P(r)$. In the present work, general important properties of the auxiliary field method are proved, such as scaling laws and independence of the results on the choice of $P(r)$. The method is extended in order to find accurate analytical energy formulae for radial potentials of the form $a P(r)+V(r)$, and several explicit examples are studied. Connections existing between the perturbation theory and the auxiliary field method are also discussed.", "revisions": [ { "version": "v1", "updated": "2008-06-12T08:42:03.000Z" } ], "analyses": { "keywords": [ "auxiliary field method", "schrödinger equations", "extensions", "accurate analytical energy formulae", "general important properties" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics A Mathematical General", "year": 2008, "month": "Oct", "volume": 41, "number": 42, "pages": 425301 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008JPhA...41P5301S" } } }
