    "abstract": "We study the dynamical generation of entanglement for a very simple system: a\npair of interacting spins, s1 and s2, in a constant magnetic field. Two\ndifferent situations are considered:(a) s1 -\u003e\\infty, s2 = 1/2 and (b) s1 = s2\n-\u003e\\infty, corresponding, respectively, to a quantum degree of freedom coupled\nto a semiclassical one (a qubit in contact with an environment) and a fully\nsemiclassical system, which in this case displays chaotic behavior. Relations\nbetween quantum entanglement and classical dynamics are investigated.",
