    "abstract": "We construct a model which describes a recently performed experiment (Phys.\nRev. A 64, 050301(R) (2001)) in which an entangled state between two modes of a\nsingle cavity is built. Environmental effects are taken into account and the\nresults agree with the experimental findings. Moreover the model predicts, for\ndifferent conditions of the same experiment, a decoherence-free subspace. These\nconditions are analyzed and slightly different experiments suggested in order\nto test its viability.",
