It is shown that these sectors, which cannot be localised with respect to the vacuum, acquire a much better localisation, namely in spacelike cones, when viewed in front of suitable ``infravacuum'' backgrounds. These background states coincide, essentially, with a class of states introduced by Kraus, Polley and Reents as models for clouds of infrared radiation.", "revisions": [ { "version": "v2", "updated": "1999-01-09T23:53:16.000Z" } ], "analyses": { "subjects": [ "81T05", "12.20.Ds" ], "keywords": [ "infravacuum", "free massless scalar field", "background states coincide", "better localisation", "space dimensions" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "Journal of Mathematical Physics", "year": 1998, "month": "Dec", "volume": 39, "number": 12, "pages": 6353 }, "note": { "typesetting": "LaTeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "inspire": 482394, "adsabs": "1998JMP....39.6353K" } } }
