    "abstract": "We study the violations of Bell inequality for thermal states of qubits in a\nmulti-qubit Heisenberg model as a function of temperature and external magnetic\nfields. Unlike the behaviors of the entanglement the violation can not be\nobtained by increasing the temperature or the magnetic field. The threshold\ntemperatures of the violation are found be less than that of the entanglement.\nWe also consider a realistic cavity-QED model which is a special case of the\nmutli-qubit Heisenberg model.",
