    "abstract": "The system of an atom couples to two distinct optical cavities with phase\ndecoherence is studied by making use of a dynamical algebraic method. We adopt\nthe concurrence to characterize the entanglement between atom and cavities or\nbetween two optical cavities in the presence of the phase decoherence. It is\nfound that the entanglement between atom and cavities can be controlled by\nadjusting the detuning parameter. Finally, we show that even if the atom is\ninitially prepared in a maximally mixed state, it can also entangle the two\nmode cavity fields.",
