    "abstract": "We quantify the total, quantum, and classical correlations with entropic\nmeasures, and quantitatively compare these correlations in a quantum system, as\nexemplified by a Heisenberg dimer which is subjected to the change of\nenvironmental parameters: temperature and nonuniform external field. Our\nresults show that the quantum correlation may exceed the classical correlation\nat some nonzero temperatures, though the former is rather fragile than the\nlater under thermal fluctuation. The effect of the external field to the\nclassical correlation is quite different from the quantum correlation.",
