Among them, infinite series of states are given that are normalizable, expand the whole space of solutions, are spatially multi-localized and are eigenstates of a suitably defined number operator. Associated with these states new sets of coherent and squeezed states for the free particle are defined representing traveling, squeezed, multi-localized wave packets. These states are also constructed in higher dimensions, leading to the quantum mechanical version of the Hermite-Gauss and Laguerre-Gauss states of paraxial wave optics. Some applications of these new families of states and procedures to experimentally realize and manipulate them are outlined.", "revisions": [ { "version": "v3", "updated": "2011-07-01T17:13:56.000Z" } ], "analyses": { "keywords": [ "free particle", "harmonic states", "paraxial wave optics", "quantum arnold transformation", "time-dependent free" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/1751-8113/44/44/445307", "journal": "Journal of Physics A Mathematical General", "year": 2011, "month": "Nov", "volume": 44, "pages": 445307 }, "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011JPhA...44R5307G" } } }
