For a special choice of the environment coefficients, the correlated coherent states are shown to be the only states which remain pure all the time during the evolution of the considered system. These states are also the most stable under evolution in the presence of the environment.", "revisions": [ { "version": "v1", "updated": "2006-04-28T16:11:45.000Z" } ], "analyses": { "keywords": [ "open quantum systems", "damped harmonic oscillator", "special choice", "environment coefficients", "correlated coherent states" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006quant.ph..4212I" } } }
