We calculate several types of dynamical quantum amplitude and find a freezing transition at some critical time. The behavior is understood by the partition-function zeros in the complex temperature plane. We discuss the properties of the freezing phase as a dynamical chaotic phase, which are contrasted to those of the spin-glass phase in the static system.", "revisions": [ { "version": "v2", "updated": "2012-12-13T16:21:34.000Z" } ], "analyses": { "subjects": [ "05.30.Rt", "75.10.Nr", "64.70.Tg", "75.50.Lk" ], "keywords": [ "quantum quench", "dynamical singularities", "random energy model", "complex temperature plane", "glassy systems driven" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review E", "year": 2012, "month": "Nov", "volume": 86, "number": 5, "pages": "051125" }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhRvE..86e1125O" } } }
