The initial conditions break the time reversal symmetry of the solution of the equation of motion in a trivial manner. When open systems are considered then the initial conditions of the environment must be included in the effective dynamics. This is achieved by means of a generalized \u03f5-prescription where the non-uniform convergence of the limit \u03f5 \u2192 0 leaves behind a spontaneous breakdown of the time reversal symmetry.<\/jats:p>","DOI":"10.3390\/sym8040025","type":"journal-article","created":{"date-parts":[[2016,4,20]],"date-time":"2016-04-20T15:00:40Z","timestamp":1461164440000},"page":"25","source":"Crossref","is-referenced-by-count":5,"title":["Spontaneous Breakdown of the Time Reversal Symmetry"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2271-2688","authenticated-orcid":false,"given":"Janos","family":"Polonyi","sequence":"first","affiliation":[{"name":"Department of Physics and Engineering, Strasbourg University, CNRS-IPHC, 23 rue du Loess, BP28 67037 Strasbourg Cedex 2, France"}]}],"member":"1968","published-online":{"date-parts":[[2016,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1038\/246067a0","article-title":"Irreversibility as a Symmetry-breaking Process","volume":"246","author":"Prigogine","year":"1973","journal-title":"Nature"},{"key":"ref_2","unstructured":"Prigogine, I.
