    "abstract": "A system consisting of two identical single-mode cavities coupled to a common\nenvironment is investigated within the framework of algebraic dynamics. Based\non the left and right representations of the Heisenberg-Weyl algebra, the\nalgebraic structure of the master equation is explored and exact analytical\nsolutions of this system are obtained. It is shown that for such a system, the\nenvironment can produce entanglement in contrast to its commonly believed role\nof destroying entanglement. In addition, the collective zero-mode eigen\nsolutions of the system are found to be free of decoherence against the\ndissipation of the environment. These decoherence-free states may be useful in\nquantum information and quantum computation.",
