    "abstract": "The entanglement of two atoms is studied when the two atoms are coupled to a\nsingle-mode thermal field with different couplings. The different couplings of\ntwo atoms are in favor of entanglement preparation: it not only makes the case\nof absence entanglement with same coupling appear entanglement, but also\nenhances the entanglement with the increasing of the relative difference of two\ncouplings. We also show that the diversity of coupling can improved the\ncritical temperature. If the optical cavity is leaky during the time evolution,\nthe dissipative thermal environment is benefit to produce the entanglement.",
