Dias and Prata pointed out that, surprisingly, its stationary-state Wigner function does not obey the naive equation of motion, i.e. the naive stargenvalue (*-genvalue) equation. We review our recent work on this problem, that treats the infinite wall as the limit of a Liouville potential. Also included are some new results: (i) we show explicitly that the Wigner-Weyl transform of the usual density matrix is the physical solution, (ii) we prove that an effective-mass treatment of the problem is equivalent to the Liouville one, and (iii) we point out that self-adjointness of the operator Hamiltonian requires a boundary potential, but one different from that proposed by Dias and Prata.", "revisions": [ { "version": "v1", "updated": "2005-07-31T21:58:41.000Z" } ], "analyses": { "keywords": [ "infinite wall", "star-quantization", "usual density matrix", "infinite potential wall", "stationary-state wigner function" ], "tags": [ "journal article" ], "publication": { "journal": "Canadian Journal of Physics", "year": 2006, "month": "Jun", "volume": 84, "number": "6-7", "pages": 557 }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 707700, "adsabs": "2006CaJPh..84..557K" } } }
