    "abstract": "It is shown that the existence of a time operator in the Liouville space\nrepresentation of both classical and quantum evolution provides a mechanism for\neffective entropy change of physical states. In particular, an initially\neffectively pure state can evolve under the usual unitary evolution to an\neffectively mixed state.",
