    "abstract": "A pure state decoheres into a mixed state as it entangles with an\nenvironment. When an entangled two-mode system is embedded in a thermal\nenvironment, however, each mode may not be entangled with its environment by\ntheir simple linear interaction. We consider an exactly solvable model to study\nthe dynamics of a total system, which is composed of an entangled two-mode\nsystem and a thermal environment, and also an array of infinite beam splitters.\nIt is shown that many-body entanglement of the system and the environment plays\na crucial role in the process of disentangling the system.",
